Question

a denominator of a fraction is 4 more than twice the numerator .when both the numerator and denominator are decreased by 6 then the denominator became 12 time the numerator .dertermine the fraction

Answer 1

let the numerator be 'x' and
the denominator be 'y'

according to first given condition,
y=2x+4
therefore, -2x+y=4 (1)

according to 2nd condition,
y-6=12(x-6)
y-6=12x-72
12x-y=-6+72
12x-y=72 (2)
