Solve and Write Subtraction EquationsSolve and Write Subtraction EquationsObjective: To solve and write subtraction equations.

Solve and Write Subtraction EquationsSubtraction and Addition Property of Equality states if two expressions are equal to each other and the exact same thing is added to or subtracted from both sides, the two sides will remain equal.

Solve and Write Subtraction EquationsAn equation is only true if both sides are equal.

A teeter totter will only be balanced if there is equal weight on both sides.

Solve and Write Subtraction EquationsSolving an algebraic subtraction equation is the same as solving an algebraic addition equation.

Solve and Write Subtraction EquationsSolve. x 2 = 3

To Solve an Addition or Subtraction Equation. Step 1- Determine which side of the equation has the variable and a constant on the same side.

Solve and Write Subtraction EquationsSolve. x 2 = 3

Step 2 - Add the opposite of the variable side constant to both sides, making sure to line up the constants.

What is the variable side constant?
