Question

Уравнение:2,5(0,2+х)-0,5(х-0,7)-0,2=0,5

Answer 1

2,5(0,2+х)-0,5(х-0,7)-0,2=0,5
(0,5+2,5х)-(0,5х-0,35)-0,2=0,5
0,5+2,5х-0,5х+0,35-0,2=0,5
0,5-0,5+0,35-0,2=0.5х-2,5х
0,15=-2х
-0,15=2х
х=-0,075

Вроде так...

Answer 2

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

1. Expand the brackets: $$0.5 + 0.5x - 0.25x + 0.35 - 0.2 = 0.5$$ 2. Simplify by collecting like terms: $$0.25x + 0.65 = 0.5$$ 3. Subtract 0.65 from both sides: $$0.25x = -0.15$$ 4. Divide both sides by 0.25: $$x = -0.6$$

The solution is $$x = -0.6$$.

I hope this helps. If you have any other questions, feel free to ask me.Ответь+подробно.+Уравнение:2,5(0,2+х)-0,5(х-0,7)-0,2=0,5
