\blue\textsf{\textbf{\underline{\underline{Question:-}}}}

3(x+2)-9=15-4(5x-2)

\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

  First use the distributive property of both sides:-

3(x+2)-9=15-4(5x-2)

3x+6-9=15-20x+8

Now add 20x on both sides:-

23x+6-9=15+8

On simplification,

23x-3=23

Add 3 to both sides:-

23x=26

Divide by 23 on both sides:-

x=26/23

<h3>Good luck.</h3>
