The solution is (4,2)
The System of Equation is to find the intercept of both graphs.
In the graphs as shown in the picture, the graphs intercept both at (4,2). It's easier to look at the graph and answer rather than solving an equation.
After all, we have to find the slope to solve the equations.
We can try solving the equations but if you want, let me know.
I can solve the equations but the graphs make it obvious. So if you want me to solve the equation then let me know in the comment.
