6.2 Solving Linear Equations Objective: To solve linear equations
Linear equations An equation is made up of two algebraic expressions put together with an = sign. To solve an equation means to find the value of the variable that makes the statement true. For example, x = 2 is a solution to x + 3 = 5 because 2 + 3 = 5 is a true statement. Linear equations can be written in the form ax + b = c.
Solving equations by addition and subtraction If a number is being added to the variable subtract it from both sides If a number is being subtracted from the variable add it to both sides
Solving equations using multiplication and division If the number is being multiplied times the variable then divide both sides by the number If the number is dividing the variable then multiply both sides by the number. If the variable is being multiplied times a fraction then multiply both sides by the reciprocal of the fraction.
