Question

if 2(x+y)=2(x-y)=root 8 then find the value of x.

Answer 1

the value of x in this problem is root 2

Answer 2

$2(x + y) = \sqrt{8} \\ 2x + 2y = 2 \sqrt{2} .....1$
$2(x - y) = \sqrt{8} \\ 2x - 2y = 2 \sqrt{2} ....2$
adding 1 and 2 we get
$4x = 4 \sqrt{2} \\ x = \sqrt{2}$
put x=√2 in 1
$2 \times \sqrt{2} - 2y = 2 \sqrt{2} \\ 2y = 2 \sqrt{2} - 2 \sqrt{2} \\ y = 0$
Therefore, x= √2
hope this helps you :-))))
