Answer 1

x=4

Explanation:

I like to use the methods: float and ping, and escalator, instead of balancing equations.

• First we "float" the -4 to the other side to give us 3x = 8+4
  (when we take something to the other side the sign changes - this is the ping)

• Now we have 3x=12
• Then we take the 3 down so x is by itself to give x=
  `(12)/(3)` so x=4 (When we escalate the 3 down it becomes divide)

Answer 2

x = 4

Explanation:

4 x 2 = 8 , 8 - 4
