Question

How do you solve the system of equations by graphing and then classify the system as consistent or inconsistent `x-y=6` and `x+y=7`?

Answer 1

See explanation.

Explanation:

To solve a system of equations by graphing we have to plot the graphs of 2 equations on a single coordinate plane and see how the two graphs are located.

graph{(x-y-6)(x+y-7)=0 [-10,10 , -9.01, 9.02]}

The graphs have 1 common point, so the system has 1 solution.
