Answer:
- bath: $28
- hand: $16
Step-by-step explanation:
Apparently, your system of equations is supposed to be ...
- 4b -3h = 64
- 5b -6h = 44
We can multiply the first equation by 2 and subtract the second equation:
2(4b -3h) -(5b -6h) = 2(64) -(44)
3b = 84
b = 28
Using the first equation, we can find the price of a hand towel:
4b -64 = 3h
h = (4/3)(b -16) . . . . . divide by 3 and factor out 4
h = (4/3)(28 -16) = 16
Bath towels cost $28 each, and hand towels cost $16 each.
