Step-by-step explanation:
The length of a rectangular patio is 4 feet less than three times it's width. The area of the patio is 160 square feet. Find the dimensions of the patio.
This has infinitely many solutions if that is all that the question asked...
2x+3y=12
3y=-2x+12
y=(-2x+12)/3
So for any value of x you choose it will give you the corresponding y value that makes your original equation true.
12m-32=-80
12m=-80+32
12m=-48
m=-4
Answer:
No solution unless you want to solve for an imaginary number which in that case 
Step-by-step explanation:
Here you can stop and say "no solution" since you cannot square root a negative number, but if you want you can still solve for an imaginary number:
You multiply 75 by 0.8 because that is the percentage of the price you pay after 20% is taken
final answer is $60
