Answer 3

I can help you solve these equations. Here are the steps:

- For the first equation, -5.4(0.9 + 2.4x) = 72.9x, we can simplify it by using the distributive property and then collecting the terms with x on one side and the constants on the other. We get:

$$-4.86 - 12.96x = 72.9x$$ $$-85.86x = 4.86$$ $$x = -\frac{4.86}{85.86}$$ $$x \approx -0.057$$

- For the second equation, 0.4(-14 - 7x) = -4.9(-21 + 5x), we can also simplify it by using the distributive property and then collecting the terms with x on one side and the constants on the other. We get:

$$-5.6 - 2.8x = 102.9 - 24.5x$$ $$-21.7x = 108.5$$ $$x = -\frac{108.5}{21.7}$$ $$x \approx -5$$

I hope this helps you. If you have any other questions, feel free to ask me.Ответь+подробно.++Найди+икс:+-5,4(0,9+2,4x)=72,9x=?+0,4(-14-7x)=+-4,9(-21+5x)x=?Срочно+помогите​+
