Step-by-step explanation:
x = van
y = bus
12x + 9y = 456
1x + 2y = 83
(Simplify equations)
9y = -12x + 456
y = -1.3x + 456/9
2y = -x + 83
y = -1/2x + 41.5
(Find x)
-1.3x + (456/9) = -.5x + 41.5
0.8x = 9.16
(Round)
x = 11
(Find y by plugging x in)
y = -1/2(11) + 41.5
y = -5.5 + 41.5
y = 36
(Check)
12(11) + 9(36) = 456
132 + 324 = 456
1(11) + 2(36) = 83
11 + 72 = 83
