Hi there!

Here are all the steps into solving this equation for "r" :

-2r - 8 + = -5r + 12

Add 5r to each side of the equation

-2r + 5r - 8 = 12

Add 8 to each side of the equation

-2r + 5r = 20

3r = 20

Divide each side of the equation by 3

r = 6.6666...


There you go! I really hope this helped, if there's anything just let me know! :)
