Answer: x = 1/2., y = 1/3
Step-by-step explanation:
= 1.... eq 1
3/2x+2/3y=5.... eq2
from eq 2,
5/x-3/y=1
(5y -3x) / xy = 1
5y - 3x = xy
5y = xy + 3x
x(y + 3) = 5y
x = 5y/(y +3)..... eq3
From eq2,
3/2(5y/(y+3)) + 2 /3y = 5
3/(10y/y+3) + 2 /3y = 5
3 * (y+3)/10y + 2 /3y = 5
(3y + 9)/10y + 2 /3y = 5
(9y + 27 +20)/30y = 5
9y + 47 = 150y
150y - 9y = 47
141y = 47
y = 47/141
y = 1/3
From eq1,
x = 5(1/3)/(1/3 + 3)
x = 1/2
