Answer 2

Solving the Equation: 2*(0.2-0.02/(0.002+0.0002x))=3

To solve the equation 2*(0.2-0.02/(0.002+0.0002x))=3, we will follow a step-by-step approach.

Step 1: Simplify the equation by performing the operations within the parentheses.

The equation becomes: 2*(0.2-0.02/(0.002+0.0002x))=3

Step 2: Simplify the expression within the parentheses.

0.2 - 0.02/(0.002 + 0.0002x)

Step 3: Simplify the expression within the parentheses further.

0.2 - 0.02/(0.002 + 0.0002x) = 0.2 - 0.02/0.002 - 0.02/(0.0002x)

Step 4: Simplify the expression within the parentheses even further.

0.2 - 0.02/0.002 - 0.02/(0.0002x) = 0.2 - 10 - 10000/x

Step 5: Simplify the equation further.

2*(0.2 - 10 - 10000/x) = 3

Step 6: Distribute the 2 to each term within the parentheses.

2*0.2 - 2*10 - 2*(10000/x) = 3

Step 7: Simplify the equation.

0.4 - 20 - 20000/x = 3

Step 8: Combine like terms.

-19.6 - 20000/x = 3

Step 9: Isolate the variable.

-20000/x = 3 + 19.6

Step 10: Simplify the right side of the equation.

-20000/x = 22.6

Step 11: Cross-multiply.

-20000 = 22.6x

Step 12: Solve for x.

x = -20000/22.6

Using a calculator, we can find that x is approximately -884.96.

Therefore, the solution to the equation 2*(0.2-0.02/(0.002+0.0002x))=3 is x ≈ -884.96.
