Simplified answer is: 7xy+4tx
Answer:
y = c/b - (A x)/b
Step-by-step explanation:
Solve for y:
A x + b y = c
Hint: | Isolate terms with y to the left hand side.
Subtract A x from both sides:
b y = c - A x
Hint: | Solve for y.
Divide both sides by b:
Answer: y = c/b - (A x)/b
Total amount of money paid
=11 x 15
=$165
total amount of money sold
=25 x 15
=$375
difference
= 375 - 165
=$210
