Question

qs - accelerated mathematics gr 8 | quiz 3

1. which operation would you use first to solve for m in $m + p = q$

a. subtraction
b. multiplication
c. division
d. addition

Explanation:

Step1: Identify target variable

We need to isolate $n$ in $mn + p = q$.

Step2: Eliminate constant term first

The term $p$ is added to $mn$, so we use the inverse operation of addition (subtraction) to remove it first.
<Expression>Subtract $p$ from both sides: $mn + p - p = q - p$ → $mn = q - p$</Expression>

Step3: Confirm first operation

The first operation needed is subtraction to isolate the term with $n$.

Answer:

a. Subtraction
