Answer:
r=-6
Step-by-step explanation:
Question: -3+r/3=-5
1) Multiply both sides of the equation by 3:
-9+r=-15
2) Add 9 to both sides:
r=-6
Footnotes:
1) In step 1 when I multiplied both sides of the equation by 3, don't forget you also have to multiply -3 by 3 because it is not part of the fraction (which is how I got -9)
