Solve:

 $3c+5=23$  

•  $c=3$  
  

•  $c=6$  
  

•  $c=7$  
  

•  $c=18$  
  

Solve:

 $4x+7=23$  

•  $x=16$  
  

•  $x=4$  
  

•  $x=9$  
  

•  $x=12$  
  

2x + 6 = 18

• x = 12

• x = -6

• x = 6

• x = -12

4x - 5 = 11

• x = -4

• x = 6

• x = -6

• x = 4

3x - 9 = 9

• x = 0

• x = 6

• x = 18

• x = 3

 $\frac{x}{5}-13=20$  

• 145

• 165

• 180

• 190

 $\frac{x}{3}+10=15$  

• 75

• 15

• 25

• 5

Solve for s:
