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.

Answer:
8 in
Step-by-step explanation:
Area = (diagonal 1 x diagonal 2)/2
60 = (diagonal 1 x 15)/2
60 x 2 = diagonal 1 x 15
120 = diagonal 1 x 15
diaognal 1 = 120/15 = 8
Answer:
Original price of the television = $850
Step-by-step explanation:
Television price on sale = $680.00
% of sale = 20%
It means price on sale = 80% = $680.00
Original price of the television = 100% = ?
Price on 1% = 680/80 = $8.5
Original price of the television = 100% = $8.5 x 100
= $850
