F2 Solving 2 Step Equations

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

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

• isolate the variable.
• check the solution.
• guess and check.
• Combine Like Terms.

Solve 2x - 3 = 1 

• 3
• 2
• 1
• -2

Solve    2x -7 = -23

• -8
• 8
• -7

Solve    8 - 2x = 30

• -11
• 11
• -12
• 12

Solve   -5t + 9 = 24

• -3
• 3
• 12

 $x\ +\ 2x\ +\ 5\ +\ x\ =\ 25$  

•  $x\ =\ 3$  

•  $x\ =\ 4$  

•  $x\ =\ 5$  

•  $x\ =\ 6$  

Combine like terms and then solve the 2-step equation:

6x + 4 + 2x = 20

• x = 8

• x = 2

• x = 3

• x = 4

Combine like terms and solve the 2-step equation:

3x + 20 - 5 = 36

• x = 17

• x = 3.6

• x = 20.3

• x = 7

3(6x-5)

• 18x-15
• 18x+-15
• 9+15x
• 9x-15
