steps to solving 2-step equations

What is the first step for solving the Equation 16 = 5x - 9 ?

• Subtract 16 from both sides

• Subtract 9 from both sides

• Add 9 to both sides

• Add 16 to both sides

Julio went to the movies with some of his friends. The tickets cost $6.50 each, and they spent $17.50 on snacks. The total amount they paid all together was $63.00. Choose the correct Equation below to represent the total cost Julio and his friends spent.

• 6.50x + 17.50 = 63.00

• 6.50 - 17.50x = 63.00

• 6.50x - 17.50 = 63.00

Solve the following Equation:

 $-5x-25=25$  

• x = -10

• x = 10

• x = -5

• x = 5

Choose the correct mathematical equation to represent the following sentence:

Two less than seven times a number is equal to negative 10

• $2-7n=-10$
  

• $7n-2=-10$
  

Match the following equation with it's sentence in words:

 $8n-7=-20$  

• Seven minus eight times a number is -20

• Seven less than eight times a number is -20

• Eight less than seven times a number is -20

• Eight times a number less than 7 is -20

-15 = 5a +12- 2a + 6

• -11

• -3

• 10

• 7

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63

• 7x = 63

• 7x - 35 = 63

• 35x + 7 = 63

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

Solve for x

 $\frac{3+x}{4}=12$  

• x = 0

• x = 6

• x = 12

• x = 45

Solve    8 - 2x = 30

• -11

• 11

• -12

• 12
