 $\frac{x}{4}+8=10$  

•  $x=-4$  

•  $x=-8$  

•  $x=8$  

•  $x=16$  

Solve for x.

 $6\ \ =\ \ \frac{x}{4}\ +\ 2$  

• x = 16

• x = 0

• x = 4

• x = 1

• x = 8

Solve for a.
 $7\ +\ \frac{a}{3}\ \ =\ \ 5$  

• a= -2

• a= -6

• a= 3

• a= 15

Solve for w.

 $\frac{w}{3}\ +\ 6\ \ =\ \ 8$  

• w = 2

• w = 4

• w = 6

• w = 8

What are the steps to solve for b in the equation below?

5b - 6 = 24

• Add 6 to both sides then divide both sides by 5

• Add 6 to both sides then 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

What error did the student make while working?

• Should have added 2 on both side instead of subtracting.

• Should have divided by $-2$

• There is no mistake.
