Hiii friend,
2(X-3) +3(Y-5) = 0
2X -6 +3Y -15 = 0
2X +3Y = 21.....(1)
5(X-1) +4(Y-4) = 0
5X -5 +4Y -16 = 0
5X +4Y = 21.......(2)
From equation 1 we get,
2X + 3Y = 21
2X = 21-3Y
X= 21-3Y/2.......(3)
Putting the value of X in equation (2)
5X + 4Y = 21
5 × (21-3Y/2) +4Y = 21
105 -15Y/2 +4Y = 21
105-15Y + 8Y = 21 × 2
-7Y = 42-105
-7Y = -63
Y = 63/7 = 9
Putting the value of X in equation (3)
X = 21-3Y/2 = 21 - 3 × 9/2 = 21 -27/2 = -6/2 =-3.
Hence,
X = -3 and Y = 9
HOPE IT WILL HELP YOU.... :-)
