Best ResponseYou've already chosen the best response.3substitution works pretty well in this scenario: can you solve the first equation for y?

Best ResponseYou've already chosen the best response.0so, i subtract the 2y

Best ResponseYou've already chosen the best response.3y = 72x; lets use this 'value' in the next equation

Best ResponseYou've already chosen the best response.0doesnt the 2x come before because it has an x

Best ResponseYou've already chosen the best response.3it doesnt need to, but if you like it there; we can keep it there... it gets used up in the next one regardless

Best ResponseYou've already chosen the best response.33x 2y = 14  lets use that y value in this equation and solve for 'x'

Best ResponseYou've already chosen the best response.0and for the other one i subtract the 3x

Best ResponseYou've already chosen the best response.0To solve by graphing just means, draw the two lines and see where (if ever) they intersect.

Best ResponseYou've already chosen the best response.3lets keep the other one as is and use out y value in it

Best ResponseYou've already chosen the best response.33x 2y = 14 3x 2(2x7) = 14 can you slove this ?

Best ResponseYou've already chosen the best response.0ohh wait i dnt think i can solve this because it has two # before the paratheses

amistre64

Best ResponseYou've already chosen the best response.33x 2(2x7) = 14 3x +4x +14 = 14 3x +4x +1414 = 1414 3x +4x +0 = 0 the two numbers are seperate terms, they dont interfere with each other

Best ResponseYou've already chosen the best response.33x +4x = 0 it just takes a little bit to be able to 'see' the problem :) x = 0 this is our solution

Best ResponseYou've already chosen the best response.0wait how did u get the x to = 0

amistre64

Best ResponseYou've already chosen the best response.3First step; plug in the value for y 3 2(2x7)= 14 ; now distribute the 2 thru the paranthesis

Best ResponseYou've already chosen the best response.33x +4x +14 = 14 do you see what i did there?

Best ResponseYou've already chosen the best response.0you did distributive property

amistre64

Best ResponseYou've already chosen the best response.3yes, and since that was (2) I used it in the process

amistre64

Best ResponseYou've already chosen the best response.33x +4x +14 = 14 ; now we subtract 14 from both sides 3x +4x +1414 = 1414

amistre64

Best ResponseYou've already chosen the best response.3correct; 3x +4x = 0 x = 0

Best ResponseYou've already chosen the best response.0but dnt we have to get the values bythemselfs first

amistre64

Best ResponseYou've already chosen the best response.3by themselves? what are you refering to?

amistre64

Best ResponseYou've already chosen the best response.33x+4x = 0 combine like terms 3x+4x = 1x right?

amistre64

Best ResponseYou've already chosen the best response.3yes, we do divide by 1 if we need to :) then 1x = 0 ....x = 0

Best ResponseYou've already chosen the best response.0in my multiple choices i do not have any one that has x=0

anonymous

Best ResponseYou've already chosen the best response.0they all start with 4 or 4

Best ResponseYou've already chosen the best response.3we use 0 to find the value of y now and your choices are going to be (0,y)

Best ResponseYou've already chosen the best response.0but there is no choice for that with 0.

Best ResponseYou've already chosen the best response.3remember we found that y = 2x7 right?

Best ResponseYou've already chosen the best response.3unless you gave me the wrong equation information, this is what the answer needs to be :)

Best ResponseYou've already chosen the best response.3lets see if these answers work; 3(0)2(7)=14 0+14=14

Best ResponseYou've already chosen the best response.32x+y = 7 2(0) + 7 = 7 0 +7 = 7 7=7

Best ResponseYou've already chosen the best response.3so we have the correct solution; but what are your answer to choose from look like?

Best ResponseYou've already chosen the best response.0(4,1) (4,1) (4,1) (4,1)

Best ResponseYou've already chosen the best response.3....... then either those go to a different problem; or they are simply wrong :)

Best ResponseYou've already chosen the best response.0i think they are wrong but idk.

Best ResponseYou've already chosen the best response.3there can only be one solution to lines that cross; it is the point we found (0,7)
