49x+45y=7182............(1)
x-y=66.......................(2)
multiply equation 2 by 45 and substract out of 1....
so....
49x+45y=7182
45x-45y=2970
____________
4x = 4212..
x = 4212/4
x = 1053...........(*)
put the value of equation (*) in equation (2).........
1053-y=66...
y=1053-66
y=987...........(**)..
equation (*). (**) are the answer of the question.,......
hope this helps you.......
