Simplifying Algebraic Equations
I am trying to simplify the following equation:
[3(x + 2) + 2x] - [4(y + 2) - 3(y - 2)]
This is how I'm processing it:
[3x + 6 + 2x] - [4y + 8 - 3y + 6]
[5x + 6] - [14 + y]
5x + 6 - 14 + y = 5x + y -8
However, the text gives the answer as:
5x - y - 8
So what am I doing wrong? Thanks.
