The equations are as given below.
x + y = 15
x - y = 7 + 4x - 19y
These equations can be rewritten as given below.
x+y=15
-3x+18y=7
3x+3y=45
-3x+18y=7
21y=52
y=52/21
x=15-(52/21)=263/21.

Let me tell you that this formulation in the post
"Find the ordered pair (x,y) that satisfies the system of equations"
is too wordy for Math and looks strange.
Word " ordered " is excessive.
Word " pair " is excessive.
Word " satisfies " is excessive.
Too many unnecessary words make writing unprofessional.
Much better is to say "Solve this system of equations".
Simple and convincing.
