How do you find the solution of the system of equations #14x = 7y + 21# and #-18x +9y = 36#?
In short, there is no solution to this system of equations.
Gather all unknown members on the left side, while putting constants on the right.
Simplify both equations by factoring out
The fact that this system contains the same expression on the left in its two equations and different values for a constant on the right signifies that the system has no solutions. There is no such pair of numbers
