2. Решите уравнение 8x+2x= 3,528; y-2 1/5 = 5 2/5; (28-x)+35,6=43,214;

2. Решение уравнений:

2.1. \( 8x + 2x = 3,528 \)

\( 10x = 3,528 \)

\( x = \frac{3,528}{10} \)

\( x = 0,3528 \)

2.2. \( y - 2\frac{1}{5} = 5\frac{2}{5} \)

\( y = 5\frac{2}{5} + 2\frac{1}{5} \)

\( y = 7\frac{3}{5} \)

2.3. \( (28-x) + 35,6 = 43,214 \)

\( 28 - x = 43,214 - 35,6 \)

\( 28 - x = 7,614 \)

\( x = 28 - 7,614 \)

\( x = 20,386 \)

Ответ: x = 0,3528; y = 7 3/5; x = 20,386.
