Question

Linda and Roy are solving the equation 4x + 3x − 7 = (1 + 4x) + 5x.

Linda uses a first step that results in 4x + 7 − 3x = (1 + 4x) + 5x.
Roy uses a first step that results in 4x + 3x − 7 = 1 + (4x + 5x).

Answer 1

Explanation:

To solve the equation 4x + 3x - 7 = (1 + 4x) + 5x, Linda rearranges the terms on the left side of the equation, resulting in 4x + 7 - 3x = (1 + 4x) + 5x.

On the other hand, Roy rearranges the terms on the right side of the equation, resulting in 4x + 3x - 7 = 1 + (4x + 5x).
