The third and fourth lines of this solution are optional. It could have looked Solving Linear Equations with Algebra like this: x+ 2 = 5 -2 = -2 x 3 If the constant is negative, you eliminate it with the addition property of equality. x-2= 5 +2 = +2 x = 7 Some equations like 3x= 12 have a number being multiplied by the variable. This number, which is 3 in this example, is called the coefficient. Coefficients can be eliminated with the division property of equality. 3x 12 3x 12 3 3 %3D Lr =4 x=4 The third line of this solution is optional. When the coefficient is a fraction, the multiplicative property of equality can be used. Multiply both sides of the equals sign by the reciprocal (also known as the multiplicative inverse) to eliminate the coefficient. 3 2 3 18 2 3 2 1 lx = 54 x= 27 The third line of this solution is optional. MATH FACTS When a fraction is multiplied by its reciprocal, the product is the number 1. So if the coefficient of a variable is a fraction, as in
