Question

F(x)=3/x-1; найти значение аргумента если f(x)=5

Answer 1

f(x) = 3/x-1

5 = 3/x-1

5x-5=3

5x=8

x=1,6

Answer 2

Ответ: 5=3/(х-1) или х-1=3/5=0,6 или х=1,6.

Answer 3

To find the value of the argument (x) when f(x) = 5, we can set up the equation and solve for x.

Given: f(x) = 5 and f(x) = 3/(x - 1)

We can equate the two expressions:

5 = 3/(x - 1)

To solve for x, we can start by cross-multiplying:

5(x - 1) = 3

Now, distribute 5 to both terms inside the parentheses:

5x - 5 = 3

Next, isolate the variable term:

5x = 3 + 5

5x = 8

Finally, divide both sides by 5 to solve for x:

x = 8/5

Therefore, the value of the argument (x) when f(x) = 5 is x = 8/5 or 1.6.
