To solve the equation \( x + 2.7 = 8.4 \), isolate \( x \) by subtracting 2.7 from both sides:

\[
x = 8.4 - 2.7
\]

Performing the subtraction:
\( 8.4 - 2.7 = 5.7 \).

Verification:
\( 5.7 + 2.7 = 8.4 \), which confirms the solution is correct. Among the options, **B. 5.7** matches the result.

To find the value of x, we subtract 2.7 from 8.4, which gives 8.4 - 2.7 = 5.7.
B
minimax To find the solution for the equation x + 2.7 = 8.4, we need to isolate x by subtracting 2.7 from both sides of the equation:

x + 2.7 - 2.7 = 8.4 - 2.7
x = 5.7

Therefore, the correct answer is:

B. 5.7
B
kimi To solve the equation \( x + 2.7 = 8.4 \), we need to isolate \( x \) by subtracting 2.7 from both sides of the equation:

\[ x = 8.4 - 2.7 \]

Now, let's do the subtraction:

\[ x = 5.7 \]

So the correct answer is:

B. 5.7

zhipu To solve the equation \( x + 2.7 = 8.4 \), we need to isolate \( x \). We can do this by subtracting 2.7 from both sides of the equation:

\[ x = 8.4 - 2.7 \]

Now, let's calculate the right-hand side:

\[ 8.4 - 2.7 = 5.7 \]

So, the solution to the equation is \( x = 5.7 \).

Therefore, the correct answer is:

B. 5.7

deepseekv3 To solve the equation \( x + 2.7 = 8.4 \), follow these steps:

1. Subtract 2.7 from both sides of the equation to isolate \( x \):
\[
x = 8.4 - 2.7
\]
2. Calculate the result:
\[
x = 5.7
\]

Thus, the correct solution is **B. 5.7**.
