20x = 4x +16
16x = 16
x=1
multiply the 2 into the absolute value bars. check if there are negatives. if there aren't, bars can be removed. solve as normal
If f(1) =5-2(1)
F(2)=5-2(2)
Adult ticket (a) = $5
Child ticket (c) = $2
785 tickets = $3280
a + c = 785 tickets
5a + 2c = $3280
c = 215 child tickets
a = 570 adult tickets
570 + 215 = 785 tickets
5(570) + 2(215) = $3280
There were 215 child tickets sold on Saturday
