2 step equations

Solve:

 $3c+5=23$  

•  $c=3$  
  

•  $c=6$  
  

•  $c=7$  
  

•  $c=18$  
  

Solve:

 $3c+5=23$  

•  $c=3$  
  

•  $c=6$  
  

•  $c=7$  
  

•  $c=18$  
  

Solve:

 $3c+5=23$  

•  $c=3$  
  

•  $c=6$  
  

•  $c=7$  
  

•  $c=18$  
  

Solve:

 $4x+7=23$  

•  $x=16$  
  

•  $x=4$  
  

•  $x=9$  
  

•  $x=12$  
  

What is the first step to solve this equation:

 $11-3x=44$  

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

15 = 2a + 7

• 2

• 4

• 12

• 14

Solve:

 $7+\frac{a}{3}=5$  

•  $a=-2$  
  

•  $a=-6$  
  

•  $a=3$  
  

•  $a=15$  
  

Solve:

 $33=4a-7$  

•  $a=-10$  
  

•  $a=10$  
  

•  $a=4.5$  
  

•  $a=-7$  

Which equation has x = 5 as the solution?

• x + 15 = 10

• 2x = 5

• 2x = 10

What what is the inverse operation of subtraction?

• addition

• subtraction

• multiplication

• division
