One and Second Step Equations

Solve the inequality.
x + 5 ≤ 13

• x ≥ 8

• x ≥ 18

• x ≤ 8 

• x ≤ 18 

3c + 5 = 23

• c = 3

• c = 6

• c = 7

• c = 18

4x + 7 = 23

• x = 16

• x = 4

• x = 9

• x = 12

The objective when solving an equation is to....

• isolate the variable.

• check the solution.

• guess and check.

• Combine Like Terms.

3y - 8 = 7y

• y = 4

• y = -4

• No Solution

• Infinite Solutions

10x + 9 = 4x - 9

• x = 0

• x = 3

• x = -3

• x = -18

• Add 6 to both sides

• Subtract 6 from both sides

• Multiply both sides by 3

• Divide both sides by 3

x - 8 = 5

• 13

• -13

• 3

• -3

Solve the equation
3x = 27. 

• x = 24

• x = 81

• x = 9

Solve the equation

6w = 24.

• w = 144

• w = 18
