MA.3.AR.2.2: True or False Equations.

When Solving true or false equations...

• Solve the left side first and write the answer under it.

• Solve the right side second and write the answer under it

• Compare the answers, are they the same if yes true, if not false they are not equal.

Example:

Dropdown

What numbers make this equation true? 5 x​

Select answer

=​ 10 x 3

Dropdown

Select the number that makes this equation true?

Select answer

x 9 = 6 x​ ​

Select answer

Dropdown

The equation 3 x 6 = 9 x 2 is

Select answer

because the left side equals​

Select answer

and the right side is equal to​

Select answer

Solving for Unknown
