Question

if x-y=0.9 and 11/x+y=2; then find the value of x and y

Answer 1

Answer:

Step-by-step explanation:

x+y=5.5--------(1)

x-y=0.9---------(2)

Adding( 1 )and (2) we get -->

2x= 6.4

Or, x=3.2

And y=5.5-3.2=2.3

So x=3.2

y=2.3

Answer 2

Given :

$x-y=0.9\\\\\frac{11}{x+y}=2$

To Find:

Value of x and y  

Solution:

$\frac{11}{x+y}=2$

$x+y=\frac{11}{2}$

So, $x+y=5.5 ---1$

$x-y=0.9 ---2$

Add 1 and 2

2x=5.5+0.9

2x=6.4

$x=\frac{6.4}{2}$

x=3.2

Substitute the value of x in 1

x + y = 5.5

3.2+y=5.5

y=5.5-3.2

y= 2.3

Hence The value of x is 3.2 and y is 2.3
