One Step & Two Step Equations! Solve for x! :)

One-Step

100

x + 2 = 7

x = 5

200

3n = 27

n = 9

300

k/5 = 8

k = 40

400

2x = 36.8

x = 18.4

500

n/7.2 = 22.5

n = 162

Two-Step

100

2x + 1 = 9

x = 4

200

n/3 - 4 = 6

n = 30

300

0.2k + 6 = 9

k = 15

400

c/0.8 + 2 = 17.75

c = 12.6

500

x/4 + 1/2 = 5/2

x = 8

Multi-Step

100

2(x + 1) = 14

x = 6

200

2(n + 7) = 40

n = 18

300

3(2n - 4) = 12

n = 4

400

1/2(n + 3) = 8/2

n = 5

500

0.05(6n - 3) = 0.6

n = 2.5

Methods

200

We always start our box-chart diagram with this

What is the variable

300

What is to isolate the variable

400

We use ________ operations to solve equations

What are inverse operations

500

When solving 3x - 72 = 18 algebraically... What is the 2nd operation?

The 2nd operation would be to divide by 3

Anything Goes!

100

Finish this sentence: Whatever operation you apply to one side of the equation, you must .....

... apply the same operation to the other side

200

When solving 2(n + 5) = 20 algebraically... What is the first step?

We must expand

300

Solve the following expression if x = 22

                  3x - x - (-40) = ??

What is 84

400

3x/2 + 4 = 6.25

x = 1.5

500
