Step-by-step explanation:

The solution to a system of equations by graphing is found by graphing both equations on a coordinate plane. The solution is the point at which the lines intersect.

First, put both equations in slope-intercept form:

y = x + 4    Already in slope-intercept form

x - y = 1      Isolate y.

-y = -x + 1   Multiply both sides by -1.

y = x - 1

Next, graph both lines:

(See attachment)

In this situation, the lines don't intersect, meaning there is no solution to this system.
