This document solves a system of two linear equations with two unknowns, x and y, to find the solution (x,y). It multiplies the first equation by 2 and the second equation by 8 to make the coefficients of x and y in both equations the same. It then subtracts the equations to isolate y and solves for y=5. Plugging y=5 back into the first equation and solving for x gives x=4. Therefore, the solution to the system is (x,y) = (4,5).
