Question

Решите уравнение: 0,9(b-5)-0.8(b-2)=2,3 Помогите решить.

Answer 1

0.9в-4.5-0.8в+1.6=2.3
0.9в-0.8в=2.3+4.5-1.6
0.1в=5.2
в=52

Answer 2

0,9b-4.5-0.8b+1.6=2.3
0.9b-0.8b=2.3+4.5-1.6
0.1b=5.2
b=5.2/0.1
b=52

Answer 3

I can help you solve this equation. Here are the steps:

- First, we need to distribute the coefficients 0.9 and 0.8 to the terms inside the parentheses. This gives us:

$$0.9b - 4.5 - 0.8b + 1.6 = 2.3$$

- Next, we need to combine the like terms on both sides of the equation. This gives us:

$$0.1b - 2.9 = 2.3$$

- Then, we need to isolate b by adding 2.9 to both sides. This gives us:

$$0.1b = 5.2$$

- Finally, we need to divide both sides by 0.1 to get the value of b. This gives us:

$$b = 52$$

Therefore, the solution is b = 52. I hope this helps.Ответь+подробно.+Решите+уравнение:+0,9(b-5)-0.8(b-2)=2,3++Помогите+решить.
