Question

What is the answer to -3(1+6r)=14-r

Answer 1

-3(1+6r)=14-r
-3-18r=14-r
-18r+r=14+3
-17r=17
r=-1

Answer 2

-3(1+6r)=14-r
-3 - 18r = 14 - r ...expand by using distributive property
-3 -17r = 14 ...add (r) to both sides
-17r = 17 ...add (3) to both sides
     r = -1 ....divide both sides by (-17)
