3x -4 = -16

x = -4

-6y + 12 = -66

y=13

1/2 (12x + 14) = 25

x = 3

3x + 7 - 4x = 9

x = -2

3 + d/2 = 14

d= 22

9 = -3y + 12

y = 1

4x - 3 = -11

x= -2

Lianna saves $25 every month in her savings account. She took out $100 on time to go shopping. She now has $450 in her account. Write and solve an equation to determine how many months Lianna has been saving money.

25m - 100 = 450; m= 22 months

-2(x - 5) = -16

x = 13

-5(m - 5) = -40

m = 13

A waiter earned $3 an hour and $45 in tips. The total amount he made was $60. Write and solve an equation to determine how many hours he worked.

3h + 45 = 60; He worked 5 hours.

-5y + (-4) = 26

y= -6

1/3 m - 5 = -6

m= -3

d/4 - 7 = -8

d= -4
