Question

| 5x -2y | - | 3x | if x = -3 and y = 2

Answer 1

|(5)(-3)-(2)(2)|-|(3)(3)|
= 10

Answer 2

If
`x = -3` and
`y = 2`, then
`|5x-2y|-|3x| = 10`

Explanation:

This is a problem that utilizes both substitution and the order of operations.

`|5x-2y|-|3x| = \\|-15-(2)(2)|-|(3)(-3)| =\\ |-15-4|-|(3)(-3)| =\\|-19|-|(3)(-3)| =\\19-|(3)(-3)| =\\19-|-9| =\\19-9 =\\10`
