One Step Equations with Adding and Subtracting Integers

What is the rule for subtracting integers?

• Rewrite as addition and follow the addition rules

• Just use the addition rules

• Add and keep the sign

• Subtract and keep the sign of the higher number.

Solve: 8(x+3)= -32

• x=1

• x= - 56/8

• x=-32/8

• x=-7

x + 12 = 20

• x = 32

• x = -32

• x = 8

• x = -8

When solving the equation
34.5 = p - 3, the first thing to do is to 

• add 3 to both sides

• add 34.5 to both sides

• subtract 3 from both sides

• subtract 34.5 from both sides

x + 40 = 56

• x = 16

• x = 96

• x = 15

• x = 10

x + 3 = 29

• x = 32

• x = 29

• x = 26

• x = 3

x - 5 = 27

• x = 32

• x = 22

• x = 135

• x = 5

t + 3.924 = 15.58

• 54.82

• 19.504

• 11.656

• 5.482

4.9 = x + 1.5

• 4.2 = x

• 6.4 = x

• 3.4 = x

• 5.8 = x

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.
