Question

solve equation, check solution r+2/5 = r-3/3

Answer 1

when you attempt to solve for r for r+2/5 = r-3/3
you would first try to get all r values to one side
r+2/5 = r-3/3
-r -r
but then you get 2/5 = -3/3
so no solution

Answer 2

r + 2/5 = r -3/3
(subtract r from both sides)
r - r + 2/5 = r - r -3/3
2/5 = 3/3

You will find this equation has no solution.
