If a point works in both equations of a linear system, then that point must be the solution to the linear system when you solve a linear system you find that one point makes both equations true what point is the solution to the system above ?

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
