Question

Сделайте так -чтобы в левой части уравнения было X - -3/x=4 P.S.:-3/x-это дробь

Answer 1

-3/х =4
4х = -3
х= -3/4
х= -0,75

Answer 2

Solving the Equation X - 3/x = 4

To solve the equation X - 3/x = 4, we can follow these steps:

1. Multiply through by x to clear the fraction. 2. Rearrange the equation to isolate x. 3. Solve for x.

Step 1: Multiply Through by x

Multiplying through by x to clear the fraction gives us:

x^2 - 3 = 4x [[9 #3]]

Step 2: Rearrange the Equation

Rearranging the equation to isolate x gives us a quadratic equation:

x^2 - 4x - 3 = 0 [[9 #3]]

Step 3: Solve for x

We can solve this quadratic equation using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

where a = 1, b = -4, and c = -3.

Plugging these values into the quadratic formula gives us:

x = (4 ± √(16 + 12)) / 2 x = (4 ± √28) / 2 x = (4 ± 2√7) / 2 x = 2 ± √7

So, the solutions for x are:

x = 2 + √7 x = 2 - √7

Therefore, the solutions to the equation X - 3/x = 4 are x = 2 + √7 and x = 2 - √7.
