Solving One-Step Equations (multiply divide)
TSWBAT solve one-step equations using
multiplication and division.
Students solve multi-step problems, including
word problems, involving linear equations and
linear inequalities in one variable and provide
justification for each step.

Notes

• Solving Equations

• Goal to get the variable by itself on one side
  of the equation. This is known as isolating the
  variable.

• This is also called solving (to solve) an
  equation.

• When we solve an equation, we find the value
  that makes the equation TRUE, called the solution.

5
Notes

• Steps for Solving Linear Equations

1. Simplify both sides of the equation.

• Distribute and/or combine like terms.

2. Collect the variables to one side of the
equation.

• Collect to the side with the greater variable.

3. Use inverse operations to isolate the
variable.

• PEMDAS backwards.

• The Golden Rule (of Mathematics)

What you do to one side, you must do to the other.
