Пошаговое объяснение:

54,3у - 12,1 + 71,6у + 42,3 - 120у​

54,3у + 71,6у - 120у​ = 12,1-42,3

5,9y=-30,2

y=-30,2/5,9 (дробью)

Answer 2

It looks like you've provided a mathematical expression with variables and constants. To simplify this expression, let's combine the terms with the same variable (y) and then combine the constant terms.

The expression you've given is:

54.3y - 12.1 + 71.6y + 42.3 - 120y

Combine the terms with 'y': (54.3y + 71.6y - 120y)

= 106.9y

Now combine the constant terms: (-12.1 + 42.3)

= 30.2

So, the simplified expression is: 106.9y + 30.2
