Now solve for a. This new equation can then. The last row in the row reduced matrix which corresponds to the equation implies that this system of equations does not have a solution.
It might seem obvious but to meaningfully solve a system of equations they must share one or more variables.
I can identify the solutions to a system of two linear equations in two. X 9 y x 9 y. Substitute the value of b into the second equation. Left begin array l 8 x 2 y 46 7 x 3 y 47 end array right.
