-0,3х=-5,1
х=17
*'-*7#*#*@&@&@,*#*#

Answer 2

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

- Subtract 0.9 from both sides of the equation: $$-0.3x+0.9-0.9=-4.2-0.9$$ - Simplify the equation: $$-0.3x=-5.1$$ - Divide both sides by -0.3: $$\frac{-0.3x}{-0.3}=\frac{-5.1}{-0.3}$$ - Simplify the equation: $$x=17$$

The solution is $$x=17$$. You can check your answer by plugging it into the original equation and verifying that both sides are equal.Ответь+подробно.+Решите+уравнение++-0.3x+0.9=-4.2
