Question

solve the equation below using balanced moves. whats the value of r?
solve below, or solve on paper and then enter your answer on zearn. whats the value of r?
2(3r - 3) = 8r + 10
r = \square

Explanation:

Step1: Expand left-hand side

$2(3r - 3) = 6r - 6$

Step2: Set equal to right-hand side

$6r - 6 = 8r + 10$

Step3: Subtract $6r$ from both sides

$-6 = 2r + 10$

Step4: Subtract 10 from both sides

$-16 = 2r$

Step5: Divide by 2 to solve for $r$

$r = \frac{-16}{2}$

Answer:

$r = -8$
