Question

4,8/x(дроь)=-1,2/5(дробь)

Answer 1

4,8/x=-1,2/5
х=(4,8*5)/-1,2=24/-1,2=20

Answer 2

To solve the equation 4 + (8/x) = -1.2/5, we can follow these steps:

Step 1: Multiply both sides of the equation by 5 to eliminate the fraction on the right side: 5 * (4 + 8/x) = -1.2

Step 2: Distribute the 5 to both terms inside the parentheses: 20 + 40/x = -1.2

Step 3: Move the constant term to the right side by subtracting 20 from both sides: 40/x = -1.2 - 20

Simplifying: 40/x = -21.2

Step 4: Multiply both sides of the equation by x to eliminate the fraction: x * (40/x) = x * (-21.2)

Simplifying: 40 = -21.2x

Step 5: Divide both sides of the equation by -21.2 to solve for x: 40 / -21.2 = x

Simplifying: x ≈ -1.89

Therefore, the solution to the equation is x ≈ -1.89.
