Solve for x. -3x = -15 x = -5 x = 5 x = -45

x = 5

Step-by-step explanation:

Solve for x:

-3 x = -15

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 x = -15 by -3:

(-3 x)/(-3) = (-15)/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

x = (-15)/(-3)

Hint: | Reduce (-15)/(-3) to lowest terms. Start by finding the GCD of -15 and -3.

The gcd of -15 and -3 is -3, so (-15)/(-3) = (-3×5)/(-3×1) = (-3)/(-3)×5 = 5:

 x = 5

tube or goog would be a great resource to with that question
