Question

4x+2y=2
3x+y=4 explain how you got the answer pls answer it is a timed test

Answer 1

x = 3, y = -5 ( 3, -5)

Explanation:

substitution

4x+2y=2 subtract 4x

2y = - 4x + 2 divide by 2

y = -2x + 1

Plug in y = -2x + 1 for y in the equation 3x+y=4 to find x value

3x+2x + 1=4 combine like terms

x + 1 = 4 make x alone/ subtract 1 from both sides

x = 3

Plug in x=3 into y = -2x + 1 to find y value

y = -2(3) + 1 multiply -2 by 3

y = -6 +1 combine like terms

y = -5

I hope this wasn't too late and helped! :)

Answer 2

1. if you solve for y you will get y=−2x+1 and if you solve for x then you get x= −1 2 y+ 1 2
