Question

Resultado da equação literal: x(a+b)+x(a-b)=2a

Answer 1

 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.
