Description
Elimination by Addition, by Addition/Subtraction and substitution methods .... all clearly explained.
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
What’s New
