Question

complete the process of solving the equation.fill in the missing term and select the missing description. simplify any fractions.$3(r + 3) = 15LXB0r = \square$options:add 3 to both sidessubtract 3 from both sidesmultiply both sides by 3divide both sides by 3combine like terms

Explanation:

Step1: Isolate the bracket term

Divide both sides by 3:
$\frac{3(r+3)}{3} = \frac{15}{3}$
Simplify to get $r + 3 = 5$

Step2: Isolate the variable $r$

Subtract 3 from both sides:
$r + 3 - 3 = 5 - 3$

Answer:

Selected operation: Subtract 3 from both sides
$r = 2$
