Question

Which graph can be used to find the solution(s) to 8 – 4x = 2x – 4?

Answer 1

it would equal 2x if im correct

Answer 2

Answer:

The answer in the attached figure

Step-by-step explanation:

Method 1

we have

$8-4x=2x-4$

Rewrite the equation as a compound system of equations

$y=8-4x$ -----> equation A

$y=2x-4$ -----> equation B

Using a graphing tool

The solution of the system of equations is the intersection point both graphs

see the attached figure

the solution is $x=2$

Method 2

we have

$8-4x=2x-4$

Group terms that contain the same variable and move the constant to the other side of equation

$4x+2x=8+4$

Combine like terms

$6x=12$

Divide by $6$ both sides

$x=2$
