Solve the equation using multiplication or division. Check your answer. -4x = 12
To solve the equation -4x = 12, we need to divide both sides of the equation by -4.
(-4x) / -4 = 12 / -4
x = -3
To check our answer, we substitute x = -3 back into the original equation:
-4(-3) = 12
12 = 12
Both sides are equal, so x = -3 is the correct solution.
To solve the equation -4x = 12 using multiplication or division, we need to isolate the variable x.
First, we will divide both sides of the equation by -4 to isolate x.
(-4x)/(-4) = 12/(-4)
Simplifying, we get:
x = -3
To check if our answer is correct, we substitute x = -3 back into the original equation:
-4(-3) = 12
Multiplying, we get:
12 = 12
The left side is equal to the right side, so our solution x = -3 is correct.
