Solving equations with Algebra Tiles
An equation is like a scale balance. Use these tiles represent to the following values or variables:
= +1
= −1
= x and this pair represents
= 0
Represent the equation x + 2 = 5 with tiles.
- Using the "Zero Pair", isolate the variable on one side of the equation by creating "zero pairs".
Remeber to keep the scale balanced.
- Write the resulting equation. x + 2 −2 = 5 −2.
Represent the final result with tiles.
- Write the solution as an equation. x = 3.
When you have determined a value for the variable, you have solved the equation.
