Combining Like Terms and Simplifying Expressions

The video tutorial explains how to add two algebraic expressions by combining like terms. It starts with adding the y terms and then moves on to subtracting fractions. The final expression is verified to ensure accuracy.

What is the first step when adding the expressions 6y + 2 and -2/3 - y?

• Subtract the y terms.

• Multiply the expressions.

• Add the constant terms first.

• Combine the y terms.

If you have 6y and subtract y, how many y's are left?

• 5y

• 4y

• 6y

• 7y

How can the number 2 be rewritten to subtract 2/3 from it?

• 6/3

• 3/3

• 4/3

• 5/3

What is the simplified form of the expression 6y + 2 added to -2/3 - y?

• 6y + 4/3

• 5y + 4/3

• 5y + 2/3

• 5y + 6/3

What should you do after simplifying an expression to ensure accuracy?

• Ask a friend to check it.

• Verify the expression is interpreted correctly.
