Answer:
[tex]x = 10[/tex]
Explanation:
[tex]5x - 20 = 2x + 10[/tex]
Then bring the ones with x to one side and the ones without x to the other side
[tex]5x - 2x = 10 + 20[/tex]
Then you solve
[tex]3x = 30[/tex]
Now you divide both sides by 3 to make x stand alone since I think you are finding x.
[tex]x = 10[/tex]
