Answer:
<em>x = -2, y = -1</em>
Step-by-step explanation:
<u>System of Equations</u>
Solve the system:
y = 1/2x
y = -x - 3
Multiplying the first equation by 2:
2y = x
Substituting x in the second equation:
y = -2y - 3
Adding 2y:
3y = -3
y = -3/3
y = -1
And x = 2*(-1) = -2
Solution: x = -2, y = -1
The customer’s current balance after an overpayment last month is D. $174.80.
<h3>How to illustrate the information?</h3>
It should be noted that after an overpayment last month, the balance on a customer’s billing statement is −$50.00 and this month’s new charges are $124.80.
Therefore, the customer’s current balance will be:
= $124.80 - (-$50)
= $124.80 + $50
= $174.80
