10

Пошаговое объяснение:

2.8у-0.7у=0.35-21.35

2.1у=-21

у=10

Answer 3

To solve the equation for y, follow these steps:

1. Start by collecting the terms with y on one side and the constants on the other side of the equation.
2. Combine like terms.
3. Divide both sides by the coefficient of y to isolate y.

Given equation: 2.8y - 0.35 = 0.7y - 21.35

Step 1: Subtract 0.7y from both sides: 2.8y - 0.7y - 0.35 = -21.35

Combine like terms: 2.1y - 0.35 = -21.35

Step 2: Add 0.35 to both sides: 2.1y = -21

Step 3: Divide both sides by 2.1: y = -21 / 2.1 y = -10

So, the solution to the equation is y = -10.
