Question

Solve the following
equation for X.

3x - 15 = -30

Answer 1

X = -5

Explanation:

3x - 15 = -30 You want to isolate tha variable

3x= -30+15 Add 15 to -15 in order to get rid of it. All you do to one side you do to the other, so you add 15 to 30

3x= -15

x= -15÷3 Divide x by 3 in order to get rid of the 3. Do it to the other side

x=-5
