Solving Algebraic Equations Multiplication and Division

What are the TWO basic rules for solving algebraic equations?

• Whatever you do to one side of the equation, you must do on the other side of the equation.

• Always add on both sides.

• Always start on the left side, regardless of where the variable is.

• Always do the inverse operation.

What operation would you perform first and then second when solving for m in the following equation? 10 + 7m = 17

• subtract 10, divide by 7

• divide by 7, subtract 10

• multiply by 7, add 10

• add 10, multiply by 7

Choose all that correctly apply

• To solve a two step equation you first isolate the term by using addition or subtraction

• The second step to solving a two step is to isolate the variable by using multiplication or division

• To isolate a term in solving a two step equation you use multiplication or division

• to isolate a variable in solving a two step equation you use addition or subtraction
