Answer:

move like terms together

Step-by-step explanation:

-2x-4+5x = 8

-2x +5x =3x

8+4 =12

3x = 12

divide both sides by 3

x = 4

Solve for the variable, so you need to isolate/get x by itself

-2x - 4 + 5x = 8       First I want to combine like terms (-2x and 5x)

-4 + 3x = 8       (Add 4 on both sides)

3x = 12       Then divide 3 on both sides to get x by itself

x = 4
