Solve -4r + 5=25 for the value of r

First you have to set r by itself and to do this you have to subtract 5 from both sides (because 5 is positve and in order to get rid of a positive is with a negative) now we have -4r=20, now divide both sides by -4 to leave r by itself, when you do you will end up with r=-5

Hope this helps
