Solve for x and y:\(\frac{5}x+\frac{2}y=6\),\(\frac{-5}x+\frac{4}y=-3\)

Answer»

The given equations can be written as

 \(\frac{5}x+\frac{2}y=6\)........(i)
\(\frac{-5}x+\frac{4}y=-3\).......(ii)

Adding (i) and (ii), we get 

6/y = 3 ⇒ y = 2 

Substituting y = 2 in (i), we have 

5/x + 2/2 = 6 ⇒ x = 1 

Hence, x = 1 and y = 2.
