When solving an equation, the first step is to see if there are any
signs. If there are, you must change them to
signs and also change the sign of the number after it to it's
. The second step is to look for the
property. If there is nothing to
, the third step is to
like terms. Once those three steps are complete you may now begin solving the equation by
the operations in
PEMDAS order.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
