Easy to find out...
y = 3x - 17
(2,-11)....x = 2 and y = -11
now we sub
-11 = 3(2) - 17
-11 = 6 - 17
-11 = -11...correct....so it IS a solution
Answer:
I inch per hour for 2 hours = 2 inches
2 inches per hour for 6 hours = 6*2 = 12 inches
1 inch per hour for 1 hour = 1 inch
2+12+1 = 15 inches of snow total

We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144
-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
