Let x equal the # of coach tickets
Let y equal the # of first class tickets
x + y = 16
260x + 970y = 10,550
Solve and state the answer. Use the substitution method to solve this system. Solve the first equation for x.
x + y = 16
x = 16 - y
Now substitute the resulting expression into the other equation and solve for y.
260( 16 - y ) + 970y = 10,550
4160 - 260y + 970y = 10,550
Combine like terms
4160 + 710y = 10,550
Subtract 4160 from both sides
710y = 6390
divide by 710
y = 9
Substitute the value of y into the equation that we solved for x, x=17−y.
x = 17 - 9
x = 8
Therefore the answer is, 8 coach tickets and 9 first class tickets.
