Answer 3

To simplify the expression 5*(2/5x-0.7)-3*(1/3x-0.2), you can follow these steps:

1. Distribute the constants outside the parentheses to the terms inside the parentheses: 5 * 2/(5x - 0.7) - 3 * 1/(3x - 0.2)

2. Simplify the fractions inside the parentheses: (10/(5x - 0.7)) - (3/(3x - 0.2))

3. Find a common denominator for the fractions: To find a common denominator, you can multiply the denominators together: Common denominator = (5x - 0.7)(3x - 0.2)

4. Rewrite each fraction with the common denominator: (10(3x - 0.2)/(5x - 0.7)(3x - 0.2)) - (3(5x - 0.7)/(5x - 0.7)(3x - 0.2))

5. Combine the fractions: [(30x - 2)/(5x - 0.7)(3x - 0.2)] - [(15x - 2.1)/(5x - 0.7)(3x - 0.2)]

6. Since the denominators are the same, you can now subtract the fractions: [(30x - 2 - (15x - 2.1))/(5x - 0.7)(3x - 0.2)]

7. Simplify the numerator: (30x - 15x - 2 + 2.1)/(5x - 0.7)(3x - 0.2)

8. Combine like terms in the numerator: (15x + 0.1)/(5x - 0.7)(3x - 0.2)

So, the simplified expression is: (15x + 0.1)/(5x - 0.7)(3x - 0.2)
