Answer:

The answer in the attached figure

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
