X+y+z=92
y=3x
z=2x-10
subsitute
x+3x+2x-10=92
6x-10=92
add 10 to both sdies
6x=102
divide by 6
x=17
subsitute
y=3x
y=3(17)
y=51
z=2x-10
z=2(17)-10
z=34-10
z=24
x=17
y=51
z=24
the numbers are 17,51,24

Answer:
\/
Step-by-step explanation:
Let x = number of half-gallons the store bought
(x-15) is the number of half-gallons the store sold
Profit = Income - Cost
$65.72 = (x-15)*3.96 - (x)2.60
65.72= 3.96x - 59.40 - 2.60x [distribute]
125.12 = 1.36x [collect terms]
92 = x
Nope. They are not equal.
