Solve the system of equations
−4x+3y=−2
y=x−1
x =
y =
1 answer:
Answer: x = -1 and y = -2
Step-by-step explanation:
So if you know y = x-1 you can plug that in where y is in the first equation
-4x + 3(x-1) = -2
Distribute the 3:
-4x +3x -3 = -2
Combine like terms:
-x -3 = -2
Add 3 to both sides:
-x = 1
Multiply by -1:
X = -1
Then you plug that into the other equation to get y=(-1)-1
Which is -2

$ 12 per hr for the first 35 hrs.....12 * 35 = 420
420 + 18x = 636
18x = 636 - 420
18x = 216
x = 216/18
x = 12
