Solving Equations and Visual Models

To provide a visual representation of equations

To confuse students

To make equations more complex

To eliminate the need for solving equations

An unbalanced equation

A diagram with no mathematical significance

A balanced equation with equal weights on both sides

A complex algebraic expression

h = 14 + 9

9h = 14

h - 9 = 14

h + 9 = 14

Multiply both sides by 9

Subtract 9 from both sides

Add 9 to both sides

Divide both sides by 9

6 + c = 24

c - 6 = 24

c + 6 = 24

6c = 24

Divide both sides by 6

Subtract 6 from both sides

Multiply both sides by 6

Add 6 to both sides
