5х+2/5х=0

To solve for x in the equation 5x + 2/5x = 0, we can start by getting rid of the fractional term. We can do this by multiplying the entire equation by the denominator, which is 5x.

(5x) * (5x + 2/5x) = (5x) * 0

Simplifying this equation gives us:

25x^2 + 2 = 0

Now, we can solve for x by moving the constant term to the other side of the equation:

25x^2 = -2

Dividing both sides by 25 gives us:

x^2 = -2/25

To isolate x, we can take the square root of both sides:

x = ± √(-2/25)

Since the square root of a negative number is not a real number, there are no real solutions to this equation.
