Problem

3x - 12 = 48

X=20 is the answer to this problem

x = 20

Step-by-step explanation:

To solve this, your goal should be to get x by itself in front of the equal sign. To do this, first add 12 to both sides of the equal sign. This gets rid of the - 12 since - 12 + 12 = 0.

3x - 12 + 12 = 48 + 12

3x = 60

The last step is to divide 3 from both sides.

3x / 3 = x.

60 / 3 = 20.

This leaves you with x = 20 which is the answer.
