add solve for x then solve for y I think it will be easier

I think adding two equation will give you in x terms only... no ned to go in a roundabout way

by using the elimination method ... Oh okay @gerryliyana then plug that in to x in x+y=4 ?
 2 years ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.1
yes... first you nd to eliminate one variable... sinc there are two equations and two unknowns.. it would is possible... but you won't get 0.3333.. in this case

NO!!! you have two use the equations which are available to you

Try using substitution and see if you got the same as me. (:

@jazy you made a mistake here Solve for x in the first equation. x + y = 4 Subtract y. x = 4  y Substitute the value of x into the second equation. Solve for y. 2(4  y) = 5  mistake
 2 years ago

gerryliyana Group TitleBest ResponseYou've already chosen the best response.1
be careful @jazy 2(4  y) = 5 ???? the right is 2(4  y)  y= 5

@jazy THANK YOU!!! it makes sence but @Rosh007 how is it a mistake?

be careful @jazy the mistake at 2(4  y) = 5 ???? the right is 2(4  y)  y= 5

@gerryliyana Thank youuuu!!:) for catching that mistake, i fixed it on my paper!

jazy Group TitleBest ResponseYou've already chosen the best response.0
I prefer substitution. x + y = 4 2x  y = 5 Solve for x in the first equation. x + y = 4 Subtract y. x = 4  y Substitute the value of x into the second equation. Solve for y. 2(4  y)  y = 5 Distribute. 8  2y  y= 5 Subtract 8. 2y  y = 3 3y = 3 Divide both sides by 3. y = 1 Now plug in the value of y(1) into any equation to solve for x. x + y = 4 x + 1 = 4 Subtract 1 x = 3  So x = 3 and y = 1

sice answer is already wrote here( which I don't like to do write directly) it is for you to know that there is a simple method than this

@Rosh007 There's an easier way ? cause you can teach it to me ..this stuff is hard for me, i'm always confused.

Rosh007 Group TitleBest ResponseYou've already chosen the best response.1
actually it is derivd from the method mentioned here.. It is actually a special case of this method.. it is applicabl here since in one equation +y and in other equation y is there actually the problem is simple x+y=4 2xy=5 dw:1353003234368:dw so when we add both equation (LHS with LHS and RHS with RHS) you get 3x =9 which can be simplified quickly and reach the answer fast

You understood?

Rosh007 Group TitleBest ResponseYou've already chosen the best response.1
actually the problem is simple x+y=4 2xy=5 add x+y+2xy = 5+4 3x+0 = 9 3x =9 if you substitute the value of x in equn 1 you get th value of y....
