# Yuet solved the equation 6a-2b=12 for a. Her steps are shown below.1. Subtract 2b: 6a = 12 - 2b 2. Divide by 6: a = 2 - 1/3b Which statement about Yuet’s work is true? In step 1 she needed to add 2b to both sides of the equation.In step 1 she needed to divide by 2b on both sides of the equation.In step 2 she needed to divide both sides of the equation by 6.In step 2 she needed to subtract 6 from both sides of the equation.

Accepted Solution

A:

Answer:In step 1 she needed to add 2b to both sides of the equation.Step-by-step explanation:When unwanted terms are added, you undo that addition by adding their opposite.Here, the unwanted term -2b is added, so the appropriate step is to add its opposite, 2b, to both sides of the equation.
