Question

based on equations reducible to linear equations solve for x and y . pls urgent....​

Answer 1

Given Equation is x - y/xy = 9

x - y = 9xy  ----- (1)  

Given Equation is x + y/xy = 5  

x + y = 5xy  ---- (2)  

On solving (1) & (2), we get  

x - y = 9xy  

x + y = 5xy  

----------------  

2x = 14xy

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

y = 1/7.  

Substitute y = 1/7 in (1), we get  

x - y = 9xy  

x - (1/7) = 9x(1/7)  

x - 1/7 = 9x/7  

7x - 1/7 = 9x/7  

On cross-multiplication, we get

7(7x - 1)/7 = 9x  

49x - 7/7 = 9x  

49x - 7 = 9x * 7     (The value in the denominator will be moved to RHS - Right hand side).

49x - 7 = 63x  

-14x = 7  

x = -1/2.  

Therefore the value of x = -1/2, y = 1/7.  

Hope this helps!
