3 x / 5 + y / 2 = 13/10 / * 10
0.5 y + 0.04 x = 2.42 / * 100
---------------------------------------
6 x + 5 y = 13 / * ( - 10 )
4 x + 50 y = 242
-------------------------------
- 60 x - 50 y = - 130
+
4 x + 50 y = 242
-----------------------------
- 56 x = 112
x = 112 : ( - 56 ) = - 2
-12 + 5 y = 13
5 y = 25
y = 25 : 5 = 5
Answer:
x = -2, y = 5.
