Question

The solution of the equation given below are x- y=2 and 2 by x+ y=1by5

Answer 1

Answer:

x-y=2-------------{1}

2/x+y = 1/5---------------{2}

from eq. {1} we get x=2+y

we have to substitute this value of 'x' in eq.{2}

2/(2+y+y) = 1/5

2/(2+2y) = 1/5

2/2(1+y) = 1/5 (2 in numerator and denominator get canceled)

1/(1+y) = 1/5

( by cross multiplying)

1+y = 5

y=5-1=4

▪︎y=4

substitute y value in eq.1 or eq.2

x-4=2

x=2+4

▪︎x=6

♧ x=6,y=4.♧
