In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
30x+ 8 = 128
If you subtract 8 from both sides and then divide by 30 you'll find that x=4.
If you multiply second equation with (-1) ;
17x - 2y = 25
-17x - 3y = 5
And sum of this gives ;
- 5y = 30
And -y = 6 which is also y = -6
