We can use inverse operations to solve an equation: The opposite of adding is subtracting The opposite of multiplying is dividing. To get b by itself we need to get rid of the 5 At the moment b is multiplied by 5, the opposite of multiplying by 5 is dividing by 5. To get c by itself we need to get rid of the 4 At the moment c is divided by 4, the opposite of dividing by 4 is multiplying by 4. Sometimes the answer to an equation is not a whole number. In these cases we can leave our answer as a fraction. When the unknown what we are working out appears on both sides of the equation, the first step is to get them on the same side. It is easiest to do this when we get rid of the smallest unknown, the one with the smallest number in front of it coefficient.

Solving linear equations means finding the value of the variable s given in the linear equations. It has a degree of 1 or it can be called a first-degree equation. Sometimes, we may have to find the values of variables involved in a linear equation. When we are given two or more such linear equations, we can find the values of each variable by solving linear equations. There are a few methods to solve linear equations.

Always on the lookout for fun math games and activities in the classroom? Try our ready-to-go printable packs for students to complete independently or with a partner! Here you will learn about solving equations, including linear and quadratic algebraic equations, and how to solve them. Students will first learn about solving equations in grade 8 as a part of expressions and equations, and again in high school as a part of reasoning with equations and inequalities. Solving equations is a step-by-step process to find the value of the variable. A variable is the unknown part of an equation, either on the left or right side of the equals sign. Sometimes, you need to solve multi-step equations which contain algebraic expressions. To do this, you must use the order of operations, which is a systematic approach to equation solving. When you use the order of operations, you first solve any part of an equation located within parentheses. An equation is a mathematical expression that contains an equals sign.
