Question

a+b=76, a-b=38, a/b=?

Answer 1

let a+b=76 be equation 1 and a-b=38 as equation 2
then from 1 a=76-b substitute in 1
then b=19 substitute in 1then a=57
as you asked me a/b=57/19=3
3 is the correct answer

Answer 2

a+b=76...................i

a-b=38................ii

adding I and ii,

2a=114

a=57

or b=19

hence a/b=57/19

=3
