Question

Find X when y= -2
Thank you for your help and have a blessed day

Answer 1

Answer:

x = -5

Step-by-step explanation:

$4x+y=2(x+3y)\\\\4x-2=2(x+3(-2))\\\\4x-2=2(x-6)\\\\4x-2=2x-12\\\\4x-2+2=2x-12+2\\\\4x=2x-10\\\\4x-2x=2x-2x-10\\\\2x=-10\\\\\frac{2x=-10}{2}\\\\\boxed{x=-5}$

Hope this helps.

Answer 2

Answer:

-5

Step-by-step explanation:

4x+y=2(x+3y)

plug in -2 for y: 4x+(-2)=2(x+3(-2))

solve: 4x-2=2x-12

subtract 2x from each side: 4x(-2x)-2=2x(-2x)-12

2x-2=-12

add 2 to each side: 2x-2(+2)=-12(+2)

2x=-10

divide both sides by 2: 2x(/2)=10(/2)

x=-5
