**7/x + 4y = 1**

**7 + 4y =1x**

**4y = 1x - 7**

**y = (1x - 7)/4------------------------------(1)**

**and ,**

**5/x + 2y = -1**

**5 + 2y = -1x**

**x = -5 - 2y----------------------------------(2)**

**by putting the value of x in equation (1)**

**y = { 1 (-5 - 2y )-7 } /4**

**y = - 5 - 2y - 7 / 4**

**y = - 12 - 2y / 4**

**y = - 12/4 - 2y/4**

**y = - 3 - y/2**

**y + y/2 = -3**

**(2y + 1y) /2 = -3**

**3y/2 = - 3**

**3y = - 3 * 2**

**3y = - 6**

**y = -6 / 3**

**y = -2**

**therefore value of y = -2**

**now value of x ,**

**by putting the value of y in equation (2)**

**x = - 5 - 2y**

**x = - 5 -2 * -2**

**x = - 5 + 2**

**x = - 3**

**therefore the value of x = -3**

**i hope that my answer will help u............................^_^**
