3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)
Answer:
n = P/8.75
Step-by-step explanation:
Jose’s pay (P) depends on the number (n) of hours he works.
P = 8.75n Divide both sides by 8.75
n = P/8.75
=====
P = $61.25
n = 61.25/8.75
n = 7 h
Jose worked for 7 h.
