Solving system of equations
First you must be able to show the equation graphically. By doing so you have to show any linear equations into y=mx+b form; then change any quadratic equations into factored form or vertex form. After you have algebraically changed all the equations you can then graph the equations and see where they intercept. Then that will be your solution.
There can be three type of solutions when solving for x equations that are linear and quadratic. The first one is no solution, the second is one solution, and the third is two solutions.
Equations: y= 2
y= -2x+7
The graph states that there is no solution because the equation does not touch or intercept with each other.
