Question

0,8-(15y-9,7y)=127,2

Answer 1

0,8-15у+9,7у=127,2

0,8-5,3у=127,2

-5,3у=127,2-0,8

-5,3у=126,4

у=23,85

Answer 2

To solve the equation, let's combine like terms and isolate the variable 'y' on one side of the equation:

0.8 - (15y - 9.7y) = 127.2

First, let's simplify the expression inside the parentheses:

0.8 - (15y - 9.7y) = 0.8 - 5.3y

Now, the equation becomes:

0.8 - 5.3y = 127.2

Next, let's isolate the term containing 'y' by moving the constant term (0.8) to the other side of the equation:

-5.3y = 127.2 - 0.8

-5.3y = 126.4

Now, to solve for 'y', divide both sides by -5.3:

y = 126.4 / (-5.3)

y ≈ -23.77

So, the solution for the equation is approximately y = -23.77.
