We have   2x-6=4x+4

Taking x one side and constant another side ,so we have

2x-4x=4+6

-2x=10

(-2x)/(-2)=10/(-2)

x=-5

2x-6=4x+4 (original equation)

-6=2x+4 (subract the 2x on both sides)

-10=2x (subtract the 4 on both sides)

-5=x (divide by two on both sides)

The first step is to subract the 2x to the other side. The second step is to subtract the 4. Then you divide by two. You need to get the number on one side, while the variable is on the other.
