Step-by-step explanation:
Step-by-step explanation:
7x + 8y = -12
8y=-12-7x
y=

x = 16 in the following equations:
8 × 2 = x
8 + 8 = x
4 × 4 = x
In the following equations, x = 16:
2x = 32
<em>32 ÷ 2 = x = 16
</em>x + 5 = 21
<em>21 - 5 = x = 16</em>
Since Joann receives $10 per hour for the first 35 hours, so she receives $350 (35 times $10) before she starts receiving extra hours.
Since she received $515, we know that she worked extra hours.
Let's use the variable x to represent the number of extra hours worked.
So we can write the following equation for the total payment received:

She worked 11 extra hours. Adding this to the 35 regular hours, so she worked for 46 hours.
