Question

3-(1.3y+1.2)=1.3y+1,5

Answer 1

Ответ:

Объяснение:

3-1.3у-1.2=1.3у+1.5

1.8-1.3у=1.3у+1.5

-1.3у-1.3у=1.5-1.8

-2.6у=-0.3

у=3/26

Answer 2

Let's solve the equation step by step:

1. Start by simplifying both sides of the equation: 3 - (1.3y + 1.2) = 1.3y + 1.5

2. Distribute the negative sign on the left side by multiplying -1 to each term inside the parentheses: 3 - 1.3y - 1.2 = 1.3y + 1.5

3. Combine like terms on both sides of the equation: (3 - 1.2) - 1.3y = 1.3y + 1.5

4. Calculate the values inside the parentheses on the left side: 1.8 - 1.3y = 1.3y + 1.5

5. Move the 1.3y term on the right side to the left side by adding 1.3y to both sides of the equation: 1.8 - 1.3y + 1.3y = 1.3y + 1.5 + 1.3y

6. The 1.3y on the left side cancels out: 1.8 = 2.6y + 1.5

7. Now, subtract 1.5 from both sides to isolate the term with y on the right side: 1.8 - 1.5 = 2.6y

8. Calculate the left side: 0.3 = 2.6y

9. Finally, divide both sides by 2.6 to solve for y: y = 0.3 / 2.6 ≈ 0.1154

So, the solution to the equation is approximately y ≈ 0.1154.
