8x +7y = 39 multiply everything by 2
2(8x +7y = 39)
16x +14y = 78
+4x - 14y= -68
-------------------------
20x = 10
20x /20 = 10/20
x = 1/2
Plug x into first formula
8 x + 7y =39
8(1/2) 7y=39
4+ 7y =39
4-4+7y =39-4
7y =35
7y/7 = 35/7
y = 5
(1/2, 5)
Answer:
3/10
Step-by-step explanation:
-6/4 where -6 is your y value (six down) and 4 is your x value (four to the right)
For the first 8 hours he makes $12.00 per hour.
$12.00 * 8 = $96.00
Now you have $128.00 = 16.00h + $96.00
Subtract 96 from each side:
32 = 16h
Divide both sides by 16:
h = 2
He worked 2 hours of overtime.
