Answer:
(9,126)
Step-by-step explanation:
Make sure x and y are on the same side
[tex]0.5x+0.25y=36\\16x-1y=18[/tex]
Eliminate y by multiplying the first equation by 4 then adding both equations together
[tex]2x+1y=144\\16x-1y=18\\18x=162\\x=9[/tex]
Plug the x value (9) into one of the equations
[tex]16(9)-1y=18[/tex]
Solve
[tex]16(9)-1y=18\\144-1y=18\\144=18+1y\\126=y[/tex]
x=9, y=126
