Answer 2

Answer:

x= 1   y = 2

Step-by-step explanation:

93x+15y = 123, ....................................1

15x+93y = 201.​......................................2

add two eqns

108 x + 108 y = 324

so x + y = 3 ....................................3

next sub 2 from 1

78x -78y = -78

x - y = - 1..........................................4

add 3 and 4

2x = 2   then x= 1

now by 3

1 + y = 3

y = 2
