2- Step Equations
2x + 14 = 26
x = 6
10 + 12 + 2x = 30
x = 8
2 (x + 4 ) = 22
x = 7
You bought a pencil case that cost $5 and four erasers. You spent a total of $25. How much did each eraser cost?
What is the equation.
5 + 4x = 25
x + 3x = -8
x = -2
10 - 4x = 2
x = 2
2x + x + 15 = 6
x = -3
-2 ( x + 5 ) = -4
x = -3
The cost of renting a bike is $10 to take the bike and $4 for every hour it spends in your possession. The final sum Janice paid is $30. How many hours did Janice rent the bike for?
Write an equation and solve for your answer.
10 + 4h = 30
h= 5 hours
4(y - 2) + y = -13
y = -1
2/3x -10 = -4
x = 9
x + 3x -10 + 5 = -13
x = -2
-4 (2x + 5) = -52
x = 4
Ashley bought 40 lollipops. She gave two to each of her friends. She only has 4 remaining. How many friends does she have?
Write an equation and solve for your answer.
40 - 2f = 4
f= 18 friends
65m+24=173.5
m=2.4
No, you get 180
-10 + x/3 = -12
x = -6
-5 = 5x - 2x - 6 - 5
x = 2
-14 = (2x + 3)2
x = -5
Jill sold half of her comic books and then bought sixteen more. She now has 36. With how many did she begin?
Write an equation and solve.
x/2 + 16 = 36 x = 20 comic books
Eileen's age is 33 which is 12 more than 3 times Mickey's age. How old is Mickey?
7 years old
-15 = -3/5x - 9
x = 10
3/4x - 1/2x + 2 - 10 = -10
x = -8
3 ( 2/3x - 5) = -23
x = -4
When you count by ones from any integer, you are counting consecutive integers. Using variables, three consecutive integers are n, n + 1, and n + 2. The sum of three consecutive integers is 48.
Write an equation and solve. What are the integers?
n + n + 1 + n + 2 = 48
n = 15
The integers are 15, 16, and 17.
Samantha goes to the grocery store and purchases 17 bags of raisins and a $2.97 jar of peanut butter. His total cost was $34.76. What was the cost for a bag of raisins?
Write an equation and solve.
17r + 2.97 = 34.76
r = $1.87
