Question

PLEASE HELP ME IM TIMED!!

question 1: Simplify the following expression: (7x + y) − (5x + 2y).

If the final answer is written in the form Ax + By, what is the value of B?

question 2: Simplify the following expression: (8x + 5y) − (2x − 3y).

If the final answer is written in the form Ax + By, what is the value of B?

Answer 1

1.

`(7x + y) - (5x + 2y) \\ = (7x - 5x) + (y + 2y) \\ = 2x + 3y`
The value of B is 3


2 .

`(8x + 5y) - (2x - 3y) \\ = (8x - 2x) + (5x - 3y) \\ = 6x + 2y`
The value of B is 2
