This polynomial has 4 terms
I don't know how to answer the first part but i'll solve it.
5(3+7)-5
5(10)-5
5x10-5
50-5
45
5% of 200 is 10, after six months, so total of $60? not sure though.
-2x=15-7y
x=-7.5+3.5y
-3x-8y=4
-3(7.5+3.5y)-8y=4
-22.5-10.5y-8y=4
-22.5-18.5y=4
-18.5y=4+22.5
-18.5y=26.5
y=-53/35
the fraction might not be in lowest terms.
