To solve the equation \(−17.02 = −2.3y\), divide both sides by \(-2.3\):

\[
y = \frac{-17.02}{-2.3} = \frac{17.02}{2.3}
\]

Simplifying \(17.02 \div 2.3\) (by multiplying numerator and denominator by 10 to get \(170.2 \div 23\)) gives \(7.4\). Substituting \(y = 7.4\) back into the original equation confirms the solution.

GPT-4o To solve the equation \(-17.02 = -2.3y\), follow these steps:

1. Divide both sides of the equation by \(-2.3\).

\[
y = \frac{-17.02}{-2.3}
\]

2. Perform the division:

\[
y = \frac{-17.02}{-2.3} = 7.4
\]

Therefore, the correct answer is:

A. 7.4

Explanation: −17.02 = −2.3y
Dividing both sides by −2.3, we get,
y = −17.02 / −2.3
y = 7.4
Verification:
Putting value of “y” in the equation to check if our answer is correct
−17.02 = −2.3y
−17.02 = −2.3×7.4
−17.02 = −17.02
LHS = RHS (Hence Proved that solution is correct)

Explanation: To solve the equation −17.02 = −2.3y, you need to divide both sides by -2.3. This gives y = 17.02 / 2.3 = 7.4.
A
baichuan4 To solve the equation, divide both sides by -2.3 to get the value of y:

-17.02 / -2.3 = y

7.4 = y

So the answer is:

A. 7.4
A
doubao B

−17.02 = −2.3y
y = -17.02 / (-2.3) = 7.4, but the answer should be negative since -2.3 is negative, so the answer is -7.4.
A
minimax To solve the equation −17.02 = −2.3y, we need to isolate y by dividing both sides of the equation by −2.3:

y = −17.02 / −2.3

y = 7.4

So the correct answer is:

A. 7.4
A
kimi To solve the equation \(-17.02 = -2.3y\), we need to isolate \(y\). We can do this by dividing both sides of the equation by \(-2.3\):

\[
y = \frac{-17.02}{-2.3}
\]

When we divide two negative numbers, the result is positive:

\[
y = \frac{17.02}{2.3}
\]

Now, we just need to perform the division:

\[
y = 7.4
\]

So the correct answer is:

A. 7.4

zhipu To solve the equation \( -17.02 = -2.3y \), we need to isolate \( y \). Here are the steps:

1. Divide both sides of the equation by \( -2.3 \):
\[
y = \frac{-17.02}{-2.3}
\]

2. Calculate the division:
\[
y = \frac{-17.02}{-2.3} = 7.4
\]

Therefore, the solution to the equation is \( y = 7.4 \).

To check the answer, substitute \( y = 7.4 \) back into the original equation:
\[
-17.02 = -2.3 \times 7.4
\]
Calculate the right-hand side:
\[
-2.3 \times 7.4 = -17.02
\]
Both sides of the equation are equal, confirming that our solution is correct.

So, the correct answer is:
A. 7.4
