Answer:
(x, y) = (7, -7)
Step-by-step explanation:
You can eliminate y by adding the two equations:
(3x -y) +(3x +y) = (28) +(14)
6x = 42 . . . . simplify
x = 7 . . . . . . divide by 6
You can eliminate x by subtracting the two equations:
(3x +y) -(3x -y) = (14) -(28)
2y = -14 . . . . simplify
y = -7 . . . . . . divide by 2
The solution is (x, y) = (7, -7).
Answer:
16:12 or 16 to 12
Step-by-step explanation:
Anthony's OT pay will be $118.875 and his overall pay will be $752.875.
Number of hours Anthony has to work in a week = 5 × 8 = 40 hours.
He worked for = 47.50 hours.
Overtime = 47.50 hours - 40 hours = 7.50 hours
Pay per hour = $15.85 / hour
Overtime pay (OT pay) = $15.85 × 7.50 = $118.875
Overall pay = $15.85 × 47.50 = $752.875
Therefore, Anthony's OT pay is $118.875 and his overall pay is $752.875.

Answer:
(-3, -4).
Step-by-step explanation:
-4x + y = 8
x - 5y = 17 Multiply this by 4:
4x - 20y = 68 Add this to the first equation:
-19y = 76
y = 76/-19
y = -4.
Plug this into the second equation:
x - 5(-4) = 17
x = 17 - 20
x = -3.
CHECK this result in equation 1:
-4(-3) + -4 = 8
12 - 4 = 8
8 = 8 <------ OK.
