# Examine the steps used to solve the equation. 12.5x − 10.2 = 3(2.5x + 4.2) - 6 12.5x − 10.2 = 7.5x + 12.6 − 6 12.5x − 10.2 = 7.5x + 6.6 12.5x = 7.5x + 16.8 4. 5x = 16.8 5. x = 3.36 Analyze the steps to determine which properties or procedures were used to complete each step

Accepted Solution

A:

Answer:see belowStep-by-step explanation:12.5x − 10.2 = 3(2.5x + 4.2) - 6 Use the distributive property to distribute the 312.5x − 10.2 = 7.5x + 12.6 − 6 Combine like terms12.5x − 10.2 = 7.5x + 6.6 Add 10.2 to each side of the equation by using the addition property of equality12.5x = 7.5x + 16.8Subtraction 7.5x from each side of the equation by using the subtraction property of equality 5x = 16.8 Divide by 5 on each side by using the division property of equality x = 3.36
