I need help on how to solve equations with variables on both sides.

1. 30=8 - 2x

2. 98 - 4b= -11b

3. 3p - 8= 13 - 4p

4. 9 - 2y/7 = y

5. 1/3(12 - 6x) = 4 - 2x

Add, subtract, multiply or divide both sides of the equation by the same amount unitl you get only the variable you want on one side. That is all there is to it.

For example:

30 = 8 - 2x

22 = -2x

-22 = 2x

x = -11

You should be able to do the others yourself

3p - 8= 13 - 4p

You would first add 8 to both sides of the equation.

3p = 21 - 4p

Then add 4p to both sides.

7p = 21

p = ?
