Solve 3+%28x%2B5%29+=+8x-7
3x%2B15+=+8x-7
7%2B15+=+8x-3x
22+=+5x
x=22%2F5
or
x=4.4


Give that a=-2, b+=3, and c=+5 evaluate %28a-b%29%5E2+%2A+%28c%2Bab%29:
%28-2-3%29%5E2+%2A+%285%2B%28-2%29%2A3%29
%28-5%29%5E2+%2A+%285-6%29
25%2A%28-1%29
-25


Simplify 3a%2B6a%2B5a-3b%2B4:
%283a%2B6a%2B5a%29-3b%2B4
%283%2B6%2B5%29a-3b%2B4
14a-3b%2B4



2p+%2A+3p+%2A%28-4q%29
6p%5E2+%2A%28-4q%29
