Question

m7 1b class multiplication and division with integers: writing expressions and equations question 15 of 16 (1 point) | question attempt: 1 of unlimited solve for x.
$-21 = -\frac{x}{3}$
simplify your answer as much as possible.
$x = \square$

Explanation:

Step1: Multiply both sides by -3

To solve for \( x \), we can multiply both sides of the equation \( -21 = -\frac{x}{3} \) by -3 to isolate \( x \).
\[
-21 \times (-3) = -\frac{x}{3} \times (-3)
\]

Step2: Simplify both sides

Simplify the left side: \( -21 \times (-3) = 63 \).
Simplify the right side: \( -\frac{x}{3} \times (-3) = x \).

Answer:

\( x = 63 \)
