Description

Simultaneous Equations combines interactive Coaching Calculators and Guides to take you step-by-step through the solving of a pair of simultaneous linear equations. The app features the addition method, the elimination method and the substitution method. Coefficients can be nonzero integers from -99 to 99 inclusive. You develop skills quickly as you work with the calculator and see each step of the process in detail : Addition method : - Choose which variable to eliminate - Decide how to make its coefficients opposites - Manipulate equations to make its coefficients opposites - Eliminate the variable by adding the equations - Solve resulting equation for the other variable - Back substitute into an original equation Elimination method : - Choose which variable to eliminate - Decide how to make its coefficients the same (absolute value) - Manipulate equations appropriately - Eliminate the variable by adding/subtracting equations - Solve resulting equation for the other variable - Back substitute into an original equation Substitution method : The steps if you start by solving first equation to express x in terms of y are shown here. - Solve first equation to express x in terms of y - Substitute x in second equation and solve for y - Substitute y solution back into rearranged first equation - Solve resulting equation for x Note that the Coaching Calculator shows the steps if you start by solving x or y from either equation.
