Question

0,8(2y - 3) + 5 (1,6 - 0,5y) - 2(0,8y - 1,7)=?

Answer 1

1,6у-2,4+8-2,5у-1,6у+2,4=8-2,5у
Если это уравнение,то -2,5у=8,у= -3,2.
Ответ:-3,2.

Answer 2

To simplify the expression, let's first distribute the constants and simplify the terms:

0.8(2y - 3) + 5(1.6 - 0.5y) - 2(0.8y - 1.7)

Now, distribute the constants inside each set of parentheses:

= 1.6y - 2.4 + 8 - 2.5y - 1.6y + 3.4

Now, combine like terms:

(1.6y - 2.4 - 1.6y) + (8 - 2.5y + 3.4)

The 1.6y and -1.6y cancel out, leaving:

-2.4 + 8 - 2.5y + 3.4

Now, combine the constants:

(8 - 2.4 + 3.4) - 2.5y

= 9 - 2.5y

So, the simplified expression is:

9 - 2.5y
