Exercises of Linear Equations

Linear equations can be solved by applying various operations to both sides of the equal sign so that we completely solve for the variable. This is possible because if we perform an operation on both sides of the equation, we are not actually changing the equation.

In this article, we will look at a summary of linear equations and explore various exercises in linear equations solved to master the process of solving these equations.

Summary of linear equations

Linear equations, also known as first-degree equations, are equations that have variables with a maximum power of 1. For example, the equations and are linear equations with one unknown. Linear equations with one unknown can be solved by following the following steps:

Step 1: Simplify: We simplify the given equation to facilitate its resolution. This includes removing parentheses and other grouping signs, removing fractions, and combining like terms

Step 2: Solve for the variable: We use addition and subtraction to move all the variables to one side of the equation and the constant terms to the other.

Step 3: Solve: We use division or multiplication to completely isolate the variable and obtain the solution.
