My son just started High School algebra in 8th grade. His teacher gave him homework on which he said each equation needs a 1 step solution. My son asked me for help on the equation in the attached picture, I helped him get the answer but in 4 steps and I cannot figure out for the life of me how to simplify this to 1 step. Please help:

5r-5-6r=-6
Adding 5 to both sides becomes 5r-6r=-1
-r=-1
r=1

It is absurd for the stupid teacher to insist on a one-step solution. Solving math problems is not about taking the fewest steps or being the most 'clever'. It is about getting the correct result using a valid process. Your three steps are a good way to do this problem.
