Question

The sum of 2 fractions is 11/13 and their difference is 5/13 what are the 2 fractions

Answer 1

Answer:

3/13, 8/13

Step-by-step explanation:

Think, 1 fractor is X and another is Y.

B/C, X + Y = 11/13

or X = (11-13Y)/13....... (1)

X - Y = 5/13

or X = (5+13Y)/13....... (2)

differentiate between No. 1 and No. 2

B/C,

(11-13Y)/13 = (5+13Y)/13

or 11-13Y = 5+13Y

or -13Y-13Y = 5-11

or -26Y = -6

or 26Y = 6

or Y = 6/26

or Y = 3/13

Y's value is 3/13

X's value is 8/13
