Question

4. Solve for x
please help!!

Answer 1

`- 3x = 15 \\ ( - 3x)/( - 3) = (15)/( - 3) \\ x = - 5`

Answer 2

x = -5

Explanation:

Isolate the variable x:

-3x = 15

Since x is being multiplied by -3, we must find a way to cancel it out. To cancel -3 being multipled, divide by -3 instead. Remember, whatever we do to one side of the equation, we must do to the other!

-3x ÷ -3 = 15 ÷ -3

1x = -5

x = -5
