Question

(2a - 3b)/(6ab) + (9b - 2a)/(6ab)

Answer 1

Ответ:

1/a.

Объяснение:

(2a - 3b)/(6ab) + (9b - 2a)/(6ab) =

= (2a - 3b + 9b - 2a)/(6ab) = (6b)/(6ab) = 1/a.

Answer 2

To simplify the expression (2a - 3b)/(6ab) + (9b - 2a)/(6ab), we can combine the numerators over the common denominator and then simplify further. Here's the step-by-step process:

Step 1: Combine the numerators over the common denominator: (2a - 3b)/(6ab) + (9b - 2a)/(6ab)

Step 2: Since the denominators are the same, we can add the numerators: (2a - 3b + 9b - 2a)/(6ab)

Step 3: Combine like terms: (2a - 2a - 3b + 9b)/(6ab)

Step 4: Simplify: 6b/(6ab)

Step 5: Cancel out the common factor of 6: b/(ab)

So, the simplified form of (2a - 3b)/(6ab) + (9b - 2a)/(6ab) is b/(ab).
