Solving One-Step Equations

y - 4.6 = 12

• 16.6
• 5.8
• 7.4
• Answer not Given

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

In the equation
x + 7 = 12
7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation? 

• Subtract 7 from both sides. The solution is x = 5.
• Add 7 to both sides. The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.
• Divide by 7 on both sides. The solution is x = 7/12

Solve the equation:
20.5 = x + 4

• 16.5
• 16.05
• 24.5
• 24.05

Which equation has w = 8 as the solution?

• 8w= 64
• 16w = 240
• 16 - w = 9
• 4 + w = 10

When solving 234 + N =389, what operation would you use to find the answer

• multiplication
• addition
• subtraction
• division

What is the solution for x + 9 = 21

• 10
• 12
• 11
• 13

What is the difference between an expression and equation?

• Expressions have an equal sign and equations do not have an equal sign
• Expressions do not have an equal sign and equations do have an equal sign
• There is not a difference
• Expressions do not have variables and equations have variables

What is your first step when you solve  x + 5 = 12

• Add 5 to 5 and add 5 to 5 to 12
• Subtract 5 from 5 and subtract 5 from 12
• Subtract 12 from 12 and subtract 12 from 5
• Add 12 to 12 and add 12 to 5

• Multiply by 7 on both sides

• Divide by 7 on both sides

• Multiply by 8 on both sides

• Divide by 8 on both sides
