Question

0,4(y - 5) = 0,3(y +1) + 1,2 решение

Answer 1

0,4(у-5)=0,3(у+1)+1,2

0,4у-2=0,3у+0,3+1,2

0,4у-0,3у=2+0,3+1,2

0,1у=3,5

у=3,5:0,1

у=35

Ответ: у=35

Answer 2

To solve the equation 0.4(y - 5) = 0.3(y + 1) + 1.2, follow these steps:

Step 1: Distribute the values on the right side of the equation. 0.4y - 2 = 0.3y + 0.3 + 1.2

Step 2: Combine like terms. 0.4y - 2 = 0.3y + 1.5

Step 3: Move all the y terms to one side of the equation and the constant terms to the other side to solve for y. 0.4y - 0.3y = 1.5 + 2 0.1y = 3.5

Step 4: Isolate y by dividing both sides by 0.1. y = 3.5 / 0.1 y = 35

So, the solution to the equation is y = 35.
