While there are more than two variables in this equation, it's still a linear equation because one of the variables will always be a constant (distance). Example 2 ...

For example, 0c + 1r + 2g = 10 turns into r = 10 – 2g. Substitute that value for r in the other two equations and continue like this until you’ve defined all variables in terms of just one variable, ...

3. Consistent system of linear equations: A system of linear equations is said to be consistent, if it has at least one solution. 4. Inconsistent system of linear equation: A system of linear ...
