The video tutorial explains how to solve equations by combining variables and using properties like the commutative property of addition. It demonstrates rewriting subtraction as addition and solving multi-step equations using inverse operations. The process involves combining like terms, applying the addition property of equality, and using division to isolate the variable, ultimately finding the solution to the equation.

What is the first step in solving an equation with like terms?

• Combine terms with the same variable

• Divide all terms by the same number

• Add all constants together

• Multiply all terms by the same number

How can subtraction be rewritten to simplify solving equations?

• As addition of a positive number

• As division by one

• As multiplication by zero

• As addition of a negative number

What property allows you to change the order of terms in an equation?
