This means that:

If Sunny worked x hours, then:

Total earned = $12x

Now, we know that Sunny was charged $15 for late delivery.

This means that $15 were deducted from the payment

Therefore:

Amount earned = Total earned - deducted amount

Amount earned = 12x - 15

50-38=12

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
