There is one solution:
use elimination method
5x - 7y = 12
5y - 2x = -7 ---> change equation around
5x - 7y = 12
-2x + 5y = -7
2 x ( 5x - 7y) = 2 x (12) multiply both sides by 2
5 x (-2x +5y) = 5 x (-7)
this give you
10x - 14y =24
-10x+25y = -35 add down
-----------------------------
11y = - 11 x is eliminated to find y value
y = -1 input to one of the original equations
5(-1) - 2x = -7
-5 - 2x = -7
+5 +5 add 5 to both sides
----------------------------
-2x = -2
x = 1
your coordinates for when they intersect is at (1, -1)

Answer=7 minivans
45/7=6.4
since you can't have 0.4 minivans, we round up 6.4 to 7
256 divide by 40 that will give you the quotient of 6 with a remainder of 16
