Question

q3 - accelerated mathematics gr 8 | quiz 3

1. in solving $\frac{x-r}{t}= s$ for $x$, begin by:

a. adding $r$ to both sides
b. subtracting $r$ from both sides
c. dividing both sides by $t$
d. multiplying both sides by $t$

Explanation:

Step1: Identify target variable

We need to isolate $g$ in $\frac{g+r}{x}=t$.

Step2: Eliminate denominator first

To remove $x$ from the left side, multiply both sides by $x$.
$\frac{g+r}{x} \times x = t \times x$
Simplifies to: $g+r = tx$

Step3: Isolate $g$ (next step)

After multiplying by $x$, we would subtract $r$, but the question asks for the first step.

Answer:

d. Multiplying both sides by x
