x + y = 92

x/5 + y/2 = 34     / both sides *10
10.x/5 + 10.y/2 = 340
2x + 5y = 340
__________________________________

x + y = 92        /both sides *-2
2x + 5y = 340

__________________________________

     -2x -2y = -184
+    2x +5y = 340      
           3y = 156          
             y = 32

x + y = 92
x + 32 = 92
x = 60
