Question

Solve the equation.

-21 = (m/3)

A) m = 7
B) m = -7
C) m = -63
D) m = 63

Answer 1

C) m = -63 is your answer

Explanation:

Isolate the variable (m). Note the equal sign, what you do to one side, you do to the other.

Multiply 3 to both sides

-21 = (m/3)

(-21)(3) = (m/3)(3)

m = (-21)(3)

Combine like terms. Simplify.

m = -21 * 3

m = -63

C) m = -63 is your answer
