ALinearEqn Linear Equations combines interactive Coaching Calculators and Guides to help students master the solving of linear equations.Coaching Calculators focus on one-step, two-step and multi-step equations such as x + 6 = 9, x/2 - 5 = 6 and 5x + 2 = 3x + 8 respectively with coefficients between -99 and 99.Students learn quickly as they work with the Coaching Calculator to review each step of the process in detail.The step by step guide includes many worked examples that highlight and simplify algebra that students find hard.One-stepx - 2 = 3, 5 + x = 4, 3x = -12, x/7 = 2Two-step3x + 8 = 20, x/9 + 2 = 5Multi-step4 + 9x = 2x + 18Equations with parentheses10 - 3(2 - 3x) = 2(x + 9)Equations with fractions(5/6)x - (3/4)x = 7/3Equations with decimals0.25x = 9.9 - 0.2xThe Guide also looks at Cross Multiplication as a useful shortcut.
