Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3

Answer:
230.55/8.70 = 26.5 hours (round as appropriate)
If you would like to find the difference (6y^3 + 17y - 3) - (4y^3 - 11y + 9), you can do this using the following steps:
(6y^3 + 17y - 3) - (4y^3 - 11y + 9) = 6y^3 + 17y - 3 - 4y^3 + 11y - 9 = 2y^3 + 28y - 12
The correct result would be 2y^3 + 28y - 12.
