Solving Equations

  • A solution to an equation is a number that makes the equation true.

  • Equality satisfies the reflexive, symmetric, and transitive properties.

  • If both sides of an equation are increased, decreased, multiplied, or divided by the same number, the resulting equation is equivalent to the original one and has the same solutions.

  • Use these properties to solve a formula for a variable.

  • To solve a word problem, define a variable and create an equation. Then solve that equation.
