Method 1 : -
x( a + b ) + x( a - b ) = 2a
x( a ) + x( b ) + x( a ) - x( b ) = 2a
ax + bx + ax - bx = 2a
ax + ax + bx - bx = 2a
2ax = 2a
x = 2a / 2a
x = 1
Method 2 :-
x( a + b ) + x( a - b ) = 2a
x{ 1( a + b ) + 1( a - b ) } = 2a
x{ a + b + a - b } = 2a
x{ a + a + b - b } = 2a
x{ 2a } = 2a
x = 2a / 2a
x = 1
From both the methods, value of x is 1 .
Therefore the value of x is 1.
