Answer:
x = 6 and y = 5
Step-by-step explanation:
Given: 10x+3y = 75 ....(i)
6x-5y = 11 ....(ii)
Solution:
On multiplying 5 into (i) and 3 into (ii)
50x+15y = 375 ....(iii)
18x-15y = 33 ....(iv)
On adding (iii) and (iv)
(50x+15y)+(18x-15y) = 375 + 33
=> 50x + 18x +15y -15y = 408
=> 68x = 408
x = 408/68 = 6
On putting x = 6 in (ii)
6*6-5y = 11
=> 5y = 36-11
=> 5y = 25
y = 25/5 = 5
Therefore, x = 6 and y = 5. ANS.
