2,7y+3,4y-1,2y=18,62

Let's solve the equation step by step. The equation given is: \[ 2.7y + 3.4y - 1.2y = 18.62 \] First, combine the \(y\) terms on the left-hand side: 1. Combine the coefficients: \[ 2.7 + 3.4 - 1.2 = 5.9 \] So the equation simplifies to: \[ 5.9y = 18.62 \] Next, to solve for \(y\), divide both sides by 5.9: \[ y = \frac{18.62}{5.9} \] Calculating the right side gives: \[ y \approx 3.16 \] Thus, the solution is: \[ y \approx 3.16 \]
