A system of linear equations that has one unknown is a set of equations that all depend on the same variable. An example is y = 1 + 3x and y = 4 + 7x.

You cannot solve one linear equation with two unknown variables.

It is a linear equation in two unknown variables, y and c. One linear equation in two unknowns cannot be solved, it can only be arranged so that one or the other variable is the subject of the equation. However, that requires you to identify which variable is to be made the subject of the equation.

Quite simply, the latter is a group of the former.A system of linear equations is several linear equations taken together, each using the same group of unknowns. Usually, such a system provides one linear equation for each unknown (x, y, z, et al) that must be found (more complex systems can exist, though). You can use and manipulate these linear equations as you would a single linear equation to help solve for the unknowns. One way is to reduce all but one of the unknowns so that each can be expressed in terms of the remaining unknown and then solve for the remaining unknown which would in turn give you the others.

It is not possible to solve one linear equation in two unknown variables.
