Step 1
Given a system of equations,
2x15y=45...(1)
13x12y=12...(2)
Multiplying (1) by 13 and (2) by 2.
(1)23x115y=415
(2)23xy=24
Step 2
Subtracting these equations,
115y+y=415+24
=36415
Therefore,
y=36415×1514
=26
Substituting y in (1)
2x=45+265
=6
Hence x = 3
Therefore the solution of the system of equation is x=3 and y=26.
