-4 plus 3x equals2

Answer 1

Whenever you have an equation, you always want to try and leave x alone on one side. So first you bring over the _4 to the other side by adding 4. (you always do the opposite of the equation, so that it gets eliminated from 1 side)

-4 + 3x = 2

+4 +4

3x = 6

Now you divide the number next to the x (the coefficient). So you divide both sides by 3.

x= 2

Answer 2

-4 + 3x = 2 original equation

3x = 2 + 4 isolating the variable on one side

3x = 6 addition

x = 6/3 division

x = 2 simplify
