Set up the following equations:
x is the amount of hours worked on the weekday job, and y is the amount of hours worked on the weekend job.
We'll use substitution to remove one of the variables.
Multiply the first equation by -18 to get opposite coefficients for y:
Combine these two equations together:
Divide both sides by 2 to get x by itself:
Plug in x to the first original equation:
Subtract 25 from both sides to get y by itself:
He worked
25 hours at his weekday job, and 15 hours at his weekend job.

Answer:
x = -5/2
Step-by-step explanation:
-15/2 = 3x
multiply both sides by 2:
2(-15/2) = 2(3x)
-15 = 6x
divide both sides by 6:
-15/6 = 6x/6
x = -15/6
this can be reduced to:
x = -5/2

Hello!
(ax)(0) means to multiple a by x, and then multiply that by 0
and anything times 0 is always 0
I hope this helps, and have a fantastic day!
