## What is Simultaneous Linear Equations?

A power learning aid combining Practice, Coaching Calculators and Guides to take you step-by-step through the solving of a pair of simultaneous linear equations.

The app features elimination by Addition, by Addition/Subtraction and substitution methods.

Coefficients can be nonzero integers from -999 to 999 inclusive.

You develop skills quickly as you work with the calculator and see each step of the process in detail :

Elimination by Addition :

- 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 by Addition/Subtraction :

- 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
