5x/5 = 20/5
4(4) =y - 12
16+y = 12
I think this would be an example of elimination method for solving a system of equations however I am unsure how it would transfer to substitution method thus I am needing assistance. I am needing this to be illustrated if you will in substitution but am unclear on the method and how it is done so am looking for assistance.© BrainMass Inc. brainmass.com October 4, 2022, 11:53 am ad1c9bdddf
I think your original elimination method solution is not right. I am going to try both methods for you.
1, elimination ...
