To solve the equation \(3.4 + 2.9y = 2.82\), we need to isolate the variable \(y\). Here are the steps:
- Subtract \(3.4\) from both sides:
\[ 2.9y = 2.82 - 3.4 \]
- Calculate the right side:
\[ 2.9y = 2.82 - 3.4 = -0.58 \]
- Now, divide both sides by \(2.9\) to solve for \(y\):
\[ y = \frac{-0.58}{2.9} \]
- Perform the division:
\[ y \approx -0.2 \]
Thus, the solution is:
\[ y \approx -0.2 \]
