Answer:
r=7
Step-by-step explanation:
-84+15r=3r
Subtract 15r from each side
-84+15r-15r=3r-15r
-84 = -12r
Divide each side by -12
-84/-12 = -12r/-12
7 = r
Answer:
r = 7
Step-by-step explanation:
So the reason that the answer is 7 is because in this equation you have to get all the r's on one side and the other numbers on the other side of the equal sign.
-84 + 15r = 3r
-84 = -12r
you then divide both sides of the equal sign by -12 in order to get rid of the -12 next to the r variable and when you divide the negative 84 by a negative 12 you will get a positive 7 giving you the answer r = 7
