Answer:x=8 and y=2
Step-by-step explanation:
To find 2x-4y=8 and 3x+6y=36
Solve simultaneously
Using elimination method
6x-12y=24
6x+12y=72
To eliminate x
-24y=-48
Divide through by -24
y=2
To get x
Substitute for y in equation 1
2x-4(2)=8
2x=8+8
2x=16
Divide through by x
x=8
Answer:
In one gallon, there are four quarts. 1 quart is 0.5 pints. 1 cup is 0.25 quartz

Answer is $155 for the job
Step by step
You can use y intercept formula for this one.
Y = mx + b
Y = Dollars earned, what you are looking for.
M= rate per hour (27)
X = hours worked (5)
B = flat rate (20)
y = (27) (5) + 20
y = $155
