Ответ:х=0,5

Пошаговое объяснение: 100% верно решено!!! не забудь подписаться!!!

0,2(5x - 6) + 3x = 0,8

х-1,2+3х=0,8

х+3х-1,2=0,8

4х-1,2=0,8

4х=1,2+0,8

4х=2

х=2:4

х=0,5

0,2(5*0,5 - 6) + 3*0,5 = 0,8

          0,8=0,8

Answer 2

To solve the given equation $0.2(5x - 6) + 3x = 0.8$, you can follow these steps:

1. Distribute the 0.2 on the left side: $1x - 1.2 + 3x = 0.8$

2. Combine like terms: $4x - 1.2 = 0.8$

3. Add 1.2 to both sides: $4x = 2$

4. Divide by 4: $x = \frac{2}{4}$

5. Simplify the fraction: $x = \frac{1}{2}$

So, the solution to the given equation is $x = \frac{1}{2}$.
