Best ResponseYou've already chosen the best response.14x  y = 11 2x + 3y = 5 Here's the steps to these kind of questions. Step 1: Choose one of the equation above and solve for one variable x or y (depends on your choice) Step 2: After you solve for, let's say X, you plug whatever you got for x into the second equation that you didn't began with. Step 3: When you plug in what you solved for x into the second equation, all the variables will become y. You solve for y, and you'll get a number. Plug that number to either one of the equations and see what you'll get for x. If none of that seems familiar with you, then i will do my best to help and make you understand this.

Best ResponseYou've already chosen the best response.1I'd go with the easiest and i'll choose the first equation.

Best ResponseYou've already chosen the best response.02x+3y=5 there is no negatives so its probably easier to solve

Best ResponseYou've already chosen the best response.1i'll choose the variable y because it's alone by itself. We can get rid of negatives when we divide both sides by negative :)

Best ResponseYou've already chosen the best response.1\(\large 4x  y = 11 \) Subtract both sides by 4x \(\large 4x4x  y = 114x \) \(\large  y = 114x \) Divide both sides by 1 \(\Large \frac{ y}{1} = \frac{114x}{1} \) \(\large y = 11+4x \)

Best ResponseYou've already chosen the best response.014x ? im sorry im so confused on this, and my teacher isnt responding

Best ResponseYou've already chosen the best response.1Why 14 x? We can't add 11 with 4x because they are different terms. Y is equal to 11+4x, that's the only info we know

Best ResponseYou've already chosen the best response.1Yes. But let's not deal with x since we are dealing with y. So, in different wording, we take whatever we got for y and plug it for the y in the second equation. Makes sense?

Best ResponseYou've already chosen the best response.1y=11+4x Our second equation is 2x+3y=5 \(\large 2x+3(11+4x)=5 \)

Best ResponseYou've already chosen the best response.02x+33+12x=5 ? or do you not use distributive property

Best ResponseYou've already chosen the best response.1Yes, you already distributed it

Best ResponseYou've already chosen the best response.2yup, you're right so far, now let's keep going right now we have: 2x+33+12x=5 now add the x's together: 2x + 12x = __x fill in the blank

Best ResponseYou've already chosen the best response.0how do i solve that? add or multiply?

Vocaloid

Best ResponseYou've already chosen the best response.2yes, so now we have 14x + 33 = 5 subtract 33 from each sign

Best ResponseYou've already chosen the best response.0am i supposed to subtract 33 from 33 too or no

Vocaloid

Best ResponseYou've already chosen the best response.2not quite, remember that you can't combine variables and numbers 14x + 33  33 = 14x 5  33 = 28 14x = 28, make sense so far?

Best ResponseYou've already chosen the best response.214x = 28 divide both sides by 14

Best ResponseYou've already chosen the best response.2good, we're almost done we know that x = 2 now, so we can find y let's go back to our first equation: 4x  y = 11 can you tell me what y is now?

Vocaloid

Best ResponseYou've already chosen the best response.2not quite. let's try plugging in 2 into the equation 4*(2)  y = 11 8  y = 11 now can you tell me what y is?

Best ResponseYou've already chosen the best response.28  y = 11 add 8 to both sides, what do you get?

Vocaloid

Best ResponseYou've already chosen the best response.2add, not subtract 11 + 8 = ?

Vocaloid

Best ResponseYou've already chosen the best response.2right, so y = 3 what is y?

Vocaloid

Best ResponseYou've already chosen the best response.2boom, we're done x = 2 and y = 3 our solution is (2,3)

Best ResponseYou've already chosen the best response.0Solve the system of equations by substitution. What is the solution for x? 2x + y = 1 4x + 2y = 2 can you help with this one too?
