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

What's the question?

x=4

Step-by-step explanation:

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

combine like terms

3x+2=2x+6

then you subtract to have variable on one side of equation

3x+2=2x+6

-2x - 2x

1x+2=6

next, you subtract to isolate the variable

1x+2=6

-2 - 2

the equation is now:

1x=6

divide each side by 1

1x/1=6/1

x=6
