A function becomes 14, when 2 is subtracted from the numerator and 3 is added to the denominator. Represent this situation as a linear equation in two variables. Also find two solutions for this.

Solution
x−2y+3=14⇒4x−8=y+3⇒4x−y=3+8⇒4x−y=11∴4x−y−11=0
is a linear equation representing x and y as two variables.
Now,
When x=0,y=−11 and when y=0, x=114
Hence, (0,−11) and (114,0) are the two solutions for this equation.
