What is the first step in solving a system by graphing? Systems of Equations Calculator is a calculator that solves systems of equations step-by-step. Each point on the line is a solution to the equation. If the two lines are identical, the system has infinite solutions and is a dependent system. A consistent system of equations has at least one solution. In the applet below, note the system of equations displayed. In order for a linear system to have a unique solution, there must be at least as many equations as there are variables. Determine whether the ordered pair [latex]\left(8,5\right)[/latex] is a solution to the following system.
