2,7y+3,4y-1,2y=1862

To solve the equation \(2.7y + 3.4y - 1.2y = 1862\), we first need to combine the like terms on the left side.

1. Combine the coefficients of \(y\): \[ (2.7 + 3.4 - 1.2)y = 1862 \] Calculate: \[ 2.7 + 3.4 = 6.1 \] Then: \[ 6.1 - 1.2 = 4.9 \]

   So we have: \[ 4.9y = 1862 \]

2. Next, divide both sides by 4.9 to solve for \(y\): \[ y = \frac{1862}{4.9} \] Doing the division: \[ y \approx 379.59 \]

Thus, the solution for \(y\) is approximately \(379.59\).
