Пошаговое объяснение:

Открываем скобки

5х-16+0,8=3х+16,2-2,6

Сложение

5х-15,2=3х+13,6

Известное вправо не известное влево(со сменой знаков)

5х-3х=13,6+15,2

2х=28,8

Х=28,8/2

Х=14,4

Answer 2

To solve the equation 5(x - 3.2) + 0.8 = 3(x + 5.4) - 2.6 for 'x', follow these steps:

1. Distribute the constants through the parentheses: 5x - 16 + 0.8 = 3x + 16.2 - 2.6

2. Combine like terms on both sides of the equation: 5x - 15.2 = 3x + 13.6

3. Subtract 3x from both sides to isolate the variable terms on one side: 2x - 15.2 = 13.6

4. Add 15.2 to both sides to isolate '2x': 2x = 28.8

5. Divide both sides by 2 to solve for 'x': x = 28.8 / 2 x = 14.4

So, the solution to the equation is x = 14.4.
