850:х=50

To solve for x, we can use the concept of cross multiplication.

Cross multiplication means multiplying both sides of the equation by the denominator of the fraction (in this case, x).

So, the equation becomes:

850 * x = 50

To isolate x on one side of the equation, we need to divide both sides by 850.

So, x = 50 / 850.

Simplifying further,

x = 1 / 17.

Therefore, the value of x is 1/17.
