Question

teacher example:
step 1: lets solve!
$5x > 15$
consider the following:
a. which side of the inequality has the variable?
b. what operation is being performed (+, -, ×, ÷)?
we know that the operation is multiplication because...

Explanation:

a. Identify the side with the variable $x$.
b. Recognize the operation between 5 and $x$.

Answer:

a. The left side ($5x$) of the inequality has the variable.
b. Multiplication ($\times$) is the operation being performed. We know that the operation is multiplication because a coefficient placed directly next to a variable represents multiplication of the coefficient and the variable, so $5x$ means $5 \times x$.
