Question

which operation would you use first to solve for n in $mn + p = q$?
a. subtraction
b. addition
c. multiplication
d. division

Explanation:

Step1: Isolate the term with n

The equation is $mn + p = q$. To solve for $n$, first eliminate the constant term $p$ on the left side.

Step2: Choose the inverse operation

The term $p$ is added to $mn$, so the inverse operation is subtraction. Subtract $p$ from both sides: $mn = q - p$. Thus, the first operation is subtraction.

Answer:

a. Subtraction
