10% of all the cars is 20 limos.
20 * 10 = 200 cars total.
limos + vans + sedans = total cars
200 cars total - 20 limos - 60 vans = x sedans
x = 120 sedans
3(-3 + 5x) -1 (4 - 4x)
Simplify each term by first using the distributive property with each set of parenthesis:
3*-3 + 3*5x - 1*4 -1* -4x
Now do the multiplications:
-9 + 15x -4 + 4x
Combine like terms
15x +4x - 9 -4
19x - 13
(0,-9) or (1,-7) or (2,-5) either one would be correct
