Given the equation, 3 x + 4 x + 5 x = 11 x 3x + 4x + 5x = 11x

or, 3 x + 4 x + 5 x − 11 x = 0 3x + 4x + 5x - 11x = 0

or, x = 0 x = 0

3x+4x+5x=11x

12x=11x

12x-11x=0

x=0

You just need to do some simple Algebra to solve this:

3 x + 4 x + 5 x = 11 x 3x + 4x + 5x = 11x

12 x = 11 x 12x = 11x

12 x − 11 x = 0 12x - 11x = 0

x = 0 x = 0

We can say: 3x +4x+5x-11x=0 So :12x-11x=0 So: x=0
