4x=20-8y
x=5-2y now use this value of x in the second equation...
3(5-2y)+6y=15
15-6y+6y=15
15=15 This is true for any y or x value.
So there are infinitely many solutions as the two equations describe the same line.

The original price would be $58.75
Answer:
Step-by-step explanation:
A
y = 7 - x
y = 7 - 2
y = 5
B
y = x^2 - 1
y = (2)^2 - 1
y = 2*2 - 1
y = 4 - 1
y = 3
C
y = x + 14
I'm going to assume that you mean (x + 14)^3
y = (x + 14)^3
y = (2 + 14)^3
y = 16^3
y = 4096
If you really do mean what it says, then
y = 2 + 14^3
y = 2744 + 2
y = 2746
