Answer 1

20x+10=27x-18
20x-27x=-18-10
-7x=-28
x=28/7

Answer 2

Hola Mate!!

Here's your answer:-

$\frac{2x + 1}{3x - 2} = \frac{9}{10} \\ = > 10(2x + 1) = 9(3x - 2) \\ = > 20x + 10 = 27x - 18 \\ = > 20x - 27x = - 18 - 10 \\ = > - 7x = - 28 \\ = > x = \frac{ - 28}{ - 7} \\ = > x = 4$

Hope it helps
