Answer:
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:

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