Answer:

x= 17/5

y= 1/3

Step-by-step explanation:

Given:-

2x + 18y =8 ---------(1)

3x - 18y =9 ----------(2)

On adding (1) and (2) ------

2x + 18y =8

3x - 18y =9

---------------

5x =17

x = 17/5

Now,

Substituting 'x' value in the equation (1)--------

2x + 18y =8

=>2*17/5 + 18y =8

=>34/5 + 18y =8

=> 34 + 18y = 8*5

=> 18y = 40-34

=> 18y =6

=> y = 6/18

=> y = 1/3
