Question

0.2(7-2Y)=2.3-0.3(Y-6)

Answer 1

0.2(7-2Y)=2.3-0.3(Y-6)
1,4-0,4у=2,3-0,3у+1,8
-0,4у+0,3у=2,3+1,8-1,4
-0,1у=2,7
у=-27

Answer 2

Let's start by simplifying the left-hand side of the equation:

0.2(7-2Y) = 1.4 - 0.4Y

Now let's simplify the right-hand side of the equation:

2.3 - 0.3(Y-6) = 2.3 - 0.3Y + 0.3(6) = 3.1 - 0.3Y

So now we have the simplified equation:

1.4 - 0.4Y = 3.1 - 0.3Y

Let's simplify it further by moving all the Y terms to one side and the constant terms to the other side:

1.4 - 3.1 = 0.1Y

-1.7 = 0.1Y

Y = -17

Therefore, the solution to the equation is Y = -17.
