Answer:
x=4
Step-by-step 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=[tex]\frac{12}{3}[/tex] so x=4 (When we escalate the 3 down it becomes divide)
