Let v = the number of students in each van, and b = the number in each bus 1v + 10b = 386 7v + 5b = 232 substitution method: take the first equation and solve for v v = 386 - 10b now take that value of v and use it in the second equation 7(386-10b) + 5b = 232 2702 - 70b + 5b = 232 2702 - 65b = 232 -65b = 232-2702 -65b = -2470 b = 38 substitute that value of b into the first equation 1v + 10*38 = 386 v + 380 = 386 v = 6
