Answer:
66
Step-by-step explanation:
PEMDAS (parenthesis is first)
14-8=6
15-4=11
then you multiply
6 times 11 equals 66
A good amount I suppose :)
If you think about this equation as a line, then in order to have an infinite number of solutions is to have another equation that describes the same line.
So, for example 3y=2x-15 would be one of those.
