Answer 2

Объяснение:

0.7ab - 49 + a - 1.2ab + 47 = -0.5аb - 2 + a

Answer 3

To solve the equation, let's first combine like terms:

0,7ab - 49 + a - 1,2ab + 47 = 0

To simplify the equation, we can add or subtract the coefficients of similar terms:

(0,7ab - 1,2ab) + (a) - (49 - 47) = 0

Simplifying further:

-0,5ab + a - 2 = 0

Now we have a quadratic-like equation in terms of "ab." To solve for "ab," we can treat it as a single variable. Rearranging the equation, we get:

-0,5ab + a = 2

Multiplying both sides of the equation by -2 to eliminate the fraction, we get:

ab - 2a = -4

Adding 4 to both sides of the equation:

ab - 2a + 4 = 0

At this point, we cannot simplify the equation further without additional information or specific values for "a" and "b." If you have any additional information or specific values, please provide them, and I'll be happy to assist you further.
