x x − 1 = 20 x = 0 20 x = x − 1 20 x − x = − 1 19 x = − 1 / : 19 x = − 19 1
To find the value of x when (x-1) / x = 20, we first need to solve the equation algebraically. We can start by multiplying both sides by x to eliminate the denominator, giving us x - 1 = 20x. Next, we move all terms involving x to one side, resulting in -1 = 20x - x. Simplifying, we get -1 = 19x, and then we can divide it by 19 to isolate x, which yields x = -1/19.
The solution to the equation x x − 1 = 20 is x = − 19 1 .
