We are asked to show that the system of equations 2x-y=-4 and 8x-4y=8 has no solutions.
A system of linear equations is said to be consistent if it has solutions. If there are two linear equation in two unknowns, a system with a unique solution is said to be consistent and independent, whereas such a system with multiple solutions is consistent and dependent. A system with no solutions is inconsistent.
A linear system of two equations...
