Not sure if that is the entire question, but yes, it does. Poly comes from the Greek polus or polloi meaning much or many.
2x - 3(x-1) = -1
2x -3x + 3 = -1
-1x + 3 = -1
-1x = -4
x = 4
y = 4 - 1
y = 3
3x-6+10x+15=35
10x+3x=35-15+6
13x=26
x=2
The answer is 225 dollars because you divide 150/20=7.5 then multiply 7.5(30) and you get 225
Answer:
183/8 or 22.875
