remember you can do ANYTHING to an eqyation as long as you do it to BOTH SIDES (except divide by zero)

tr to isolate the unknown by itself

3x+3=12
minus 3 both sides
3x+3-3=12-3
3x+0=9
3x=9
divide by 3
x=3

x/4+4=8
minus 4
x/4=4
multiply 4
x=16

3x + 3 = 12

To solve these type of equations, we need to apply the inverse operation to both sides of the equation. Next, we'd isolate the variable.

Here's how it's done:

3x + 3 = 12
- 3 -3

Notice, we subtracted 3 from both sides.

3x = 9
3x/3 = 9/3
x = 3

Now for the other:
x/4+4=8
- 4 -4

8 - 4 = 4

x/4 = 4
x/4 * 4/1 = 4 * 4
x = 16

We're officially done:

1st one: x = 3
2nd one: x = 16
