Using Variables to Write and Solve Equations

Creating Equations

You can write equations to solve word problems using variables. An equation has an equals sign and shows that two things are the same.

Solving Equations

  • Find what the variable stands for.
  • Do the same thing to both sides to keep the balance.
  • Check your answer by plugging it back in.

Real-World Examples

If you know your total spending is \$30 and each movie ticket costs \$6, you can write \(6x = 30\) to find out how many tickets you bought.

Examples

  • If \(x + 5 = 12\), then \(x = 7\).

  • If 4 notebooks cost \$16, then each notebook costs $x, so \(4x = 16\).

In a Nutshell

Equations with variables help you solve unknowns in many situations.
