12/8 Solving Equations Practice

What is the solution of 9 + k = 18

• 18

• 9

• 8

• 7

What is the first step to solve this equation:

 $-3x-11=55$  

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides

What operation would you perform first and then second when solving for m in the following equation?

 $10+7m=17$  

• subtract 10, divide by 7

• multiply by 7, add 10

• divide by 7, subtract 10

• add 10, multiply by 7

Solve for a:

 $-2a+8=14$  

• a = 15

• a = 3

• a = -15

• a = -3

The steps in solving

 $5b-6=24$  are:

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

• Add 6 to both sides and 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

Solve:

 $3w=30$  

• w = 6

• w = 10

• w = 90

• w = 60

Solve:

 $-4x=24$  

• -20

• -6

• x = -20

• x = -6

Solve:

 $\frac{w}{3}+6=8$  

• w = 2

• w = 6

• w = 4

• w = 8

Write an equation:

For a field trip 4 students rode in cars and the rest filled nine buses. How many students were in each bus if 472 students were on the trip?

• $4x\ =\ 472$

• $4+9x=472$

• $9x=472$

• $4+x=472$

Mary earns $14 per hour. Which equation represents how many hours she worked to earn $112?

• $14h\ =\ 112$

• $\frac{14}{h}=112$

• $h+14=112$

• $h-14=112$
