What is the answer to the equation 5x=2x+20?
Agata [3.3K]

I don't know.  But I know how to find it.  Let's work it out together:

                                              <u>5x  =  2x + 20</u>

Subtract  2x  from each side:    3x  =  20

Divide each side by  3 :              <em>x  =  20/3</em>  or    ( 6 and 2/3 ).
