6(-3x)-x=-36
-18x-x=-36
-19x=-36
x=1.9
------------
6y-1.89=-36
6y=34.2
y=5.7
-------------
5.7=-3(1.9)

6y-x=-36
y=-3x replace y in the first equation & solve for x.
6(-3x)-x=-36
-18x-x=-36
-19x=36
x=-36/-19
x=36/19 ans.
y=-3*36/19
y=-108/19 ans.
Proof:
6*-108/19-36/19=-36
-648/19-36/19=-36
-684/19=-36
-36=-36
