Answer :
Answer:
x= 3 and y=- 5
Step-by-step explanation:
9x-5y =52.....(i)
4x-3y=27......(ii)
now we multiply equation (i) by 3 and multiply equation (ii) by 5 and then we substract . So we get ,
27x-15y =156
20x-15y = 135
if we substract two equation then y is eliminated and we get 7x=21 so x=3 and y =-5
