Step-by-Step Solution

Multiplication and division are inverse operations, so to undo × 6 you divide both sides by 6.

Answer: A) divide by 6

When the variable appears on both sides, gather all variable terms on one side and all constants on the other.

Example:

5 x + 3 = 2 x + 18

.
Move

2 x

to the left (flip):

5 x - 2 x + 3 = 18

Simplify:

3 x + 3 = 18

Move +3:

3 x = 15

Divide:

x = 5

.

**Verify**:

5 (5) + 3 = 28

;

2 (5) + 18 = 28
