Use Variables to Represent Unknowns in Simple Equations

In mathematics, variables are used to represent unknown values. These unknowns are often represented by letters like x, y, or z. By using variables, we can express problems in the form of equations and find solutions.

Steps for Solving Equations Using Variables:

1. Identify the variable: Determine which quantity is unknown and represent it with a variable.
2. Write the equation: Formulate the equation based on the information given in the problem.
3. Solve for the variable: Use arithmetic operations to find the value of the variable that satisfies the equation.

Example:

Consider the equation: x + 5 = 12. To find the value of x, subtract 5 from both sides:

x = 12 - 5

Solution: x = 7
