Is it possible to show a real life situation where these skills are used, or are these skills used say in calculus,

I just thought that rational equations must find the LCD(least common denominator) first? Then multiply every term/both sides by the LCD then Solve the variable whether it's linear or quadratic form?

Am I wrong? Please tell me more about this

(10-x)/x + 9/4=0. Multiply by 4x gives 4(10-x)+ 9 x = 0. 40 - 4x+ 9x=0. So 5x= - 40. Hence x = - 8. And.

3(x+5)-2(x+9)=0 . So 3x+15-2x-18=0. Hence x-3=0. So x=3. PSD..

2nd question,
I don't understand where u get -5 from?
Please clarify.
40/-5=-5x/-5
Thank u🙏
