Solving Linear Equations - Fractions

1.4 Solving Linear Equations - Fractions Objective: Solve linear equations with rational coefficients by multi-plying by the least common denominator to clear the fractions. Often when solving linear equations we will need to work with an equation with fraction coefficients. We can solve these problems as we have in the past.
