5x + 4 = 54
x = 10
3 + x/2 = 10
x = 14
4n + 3=15
subtract 3 from both sides
- 5(-2x + 1) = 5
x = 1
Dubuque Bike Shack rents bikes for $18 plus $8 per hour. James paid $74 to rent a bike. How many hours did he rent the bike?
7 hours
2x + 20 = 70
x = 25
-2 + x/-4 = 3
x = -20
-470 + 2n = 1100
add 470 to both sides
- 4(6x + 3) = 180
x = -8
Jenny buys a magazine for $5 and 3 pens. She spent a total of $14. How much does each pen cost?
$3.00
4x - 20 = 12
x = 8
1/2x - 2 = -15
x = -26
4x - 9 = 27
add 9 to both sides
- 5(4x + 5) = 115
x = -7
Wahlert High School is selling tickets to a dance for $16 each. If the dance costs $1280 to put on, how many tickets must they sell in order to make their money back?
80 tickets
-39 = -5x + 11
x = 10
2x - 3/4 = 5/8
x = 11/16
3(2x + 4) = 6
divide both sides by 3
or
distribute 3 with 2x and with 4
- 3(-5x + 5) = 30
x = 3
Susan is selling her dish collection. She sold half of it to one lady and 4 more dishes to another lady. How many did she start with if she now has 16 dishes left?
40 dishes
-x + 14 = -87
x = 111
-2/3x + 4 = 16
x = -18
Explain how to distribute first in this equation and what the new equation will look like.
-5(2x + 3) = 25
Multiply -5 by 2x and by 3
-10x - 15 = 25
4(-2x + 9) = - 60
x = 12
