Understanding and Verifying Solutions to Equations

Why is it important to verify your solution to a math problem?

• To ensure the answer is aesthetically pleasing

• To confirm the solution is correct

• To make the problem more challenging

• To impress your teacher

What is the first step in verifying a solution to an equation?

• Check the answer with a calculator

• Ask a friend for help

• Substitute the solution into the equation

• Simplify both sides of the equation

What does it mean if both sides of an equation are equal after substitution?

• The solution is incorrect

• The solution is correct

• The equation is unsolvable

• The equation is false

Which of the following is an example of a true equation?

• 7 = 15

• 21 = 22

• 12 = 12

• 5 = 10

What does a false equation indicate about the solution?

• The equation is balanced

• The equation is true

• The solution is incorrect

• The solution is correct

Which of the following is an example of a false equation?

• 30 = 30

• 7 = 7

• 21 = 22

• 12 = 12

In the equation y + 3 = 10, is 7 a solution?

• No, because 7 is too small

• Yes, because 7 is a lucky number

• Yes, because 7 + 3 equals 10

• No, because 7 + 3 does not equal 10

In the equation 2m - 5 = 6, is 4 a solution?

• Yes, because 2 times 4 minus 5 equals 6

• No, because 2 times 4 minus 5 does not equal 6

• Yes, because 4 is an even number

• No, because 4 is too large

What should you do if you find a false equation after substituting your solution?

• Ask someone else to solve it

• Ignore it and move on

• Celebrate your success

• Go back and check your steps

What operation should be performed first when simplifying 2 times 4 minus 5?

• Subtraction

• Division

• Addition

• Multiplication
