Exercise 10 Page 195

Apply inverse operations to isolate M.

B

To solve the given literal equation for M, we will use the Properties of Equality to apply inverse operations on the equation.

K = 3M - 7

LHS+7=RHS+7

K + 7 = 3M

.LHS /3.=.RHS /3.

K + 7/3 = M

Rearrange equation

M = K + 7/3

This corresponds to option B.
