To solve for \( y \) in the equation \( y + 2.9 = 11 \), subtract 2.9 from both sides:

\[
y = 11 - 2.9 = 8.1
\]

Testing option **A (8.1)** by substituting back into the equation confirms it satisfies \( 8.1 + 2.9 = 11 \).

baichuan4 To solve for y, we need to isolate y on one side of the equation. We can do this by subtracting 2.9 from both sides of the equation.

y + 2.9 = 11
y + 2.9 - 2.9 = 11 - 2.9
y = 8.1

Therefore, the correct answer is:
A. 8.1

doubao A. 8.1

To find the value of y, we subtract 2.9 from both sides of the equation: y = 11 - 2.9 = 8.1.

minimax To find the value of y that makes the equation y + 2.9 = 11 true, we need to isolate y on one side of the equation. We can do this by subtracting 2.9 from both sides of the equation:

y + 2.9 - 2.9 = 11 - 2.9

This simplifies to:

y = 8.1

Therefore, the correct answer is:

A. 8.1

Explanation:
To solve this equation, we need to subtract 2.9 from both sides:
y + 2.9 - 2.9 = 11 - 2.9
y = 8.1
So, the correct answer is 8.1, which corresponds to option A.

zhipu To find the value of \( y \) that makes the equation \( y + 2.9 = 11 \) true, we need to isolate \( y \). We can do this by subtracting 2.9 from both sides of the equation:

\[ y + 2.9 - 2.9 = 11 - 2.9 \]

This simplifies to:

\[ y = 11 - 2.9 \]

\[ y = 8.1 \]

So, the value of \( y \) that makes the equation true is 8.1. Therefore, the correct answer is:

A. 8.1
