Hunter Olson · Answer 1

Equation A: 14x+2y=296

Equation B: 4v+12y=736

From B: y = (736-4x) / 12

Substitute y to Equation A:

14x+2[ (736-4x) / 12]=296

14x + (1472/12) - (8x/12) = 296

14x - (8x/12) = 296 - (1472/12)

(168x-8x) / 12 = (3552-1472) / 12

x=2080/160

x=13 students van can carry

y=[736-4 (13) ]/12

y=57 students bus can carry
