Question

1. which operation is used first to solve for $f$ in $gf + h = i$?

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

Explanation:

Step1: Isolate the term with $f$

We start by eliminating the term without $f$ from the left side. The equation is $gf + h = i$. Subtract $h$ from both sides to get the term with $f$ alone.
$gf + h - h = i - h$
Simplifies to: $gf = i - h$

Step2: Solve for $f$ (not needed for the question)

Divide both sides by $g$: $\frac{gf}{g} = \frac{i - h}{g}$
Simplifies to: $f = \frac{i - h}{g}$

Answer:

a. Subtraction
