Question

(x+y)2=100, (x-y)2= 64 than find value of x​

Answer 1

Step-by-step explanation:

2x+2y=100--(1)

2x-2y=64---(2)

cancel y from both the equation

Now,

4x=36

x=36/4=9

x=9

if u want the answer for y

then sub value of x in any one of equation

(1)=> 2(9)+2y=100

18+2y=100 ( group like terms)

2y=100-18= 82

2y=82

y = 82/2 =41
