1. (13x+1) + (2x-6)

2. (-12x+8)- (2x-8)

solve each single step equation. show your work.

3.-15+n=-9

4. v/8=2

1. (13x+1) + (2x-6)

(13x + 2x) + (1 + -6)

15x - 5

2. (-12x+8)- (2x-8)

(-12x - 2x) + (8 - -8)

-14x + 16

3.-15+n=-9

-15 + n + 15 = -9 + 15

n = 6

4. v/8 = 2

v/8 * 8 = 2 * 8

v = 16

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
