which expression is not equivilent to 8+(n-4)?
12+n is different and find the reason why... :p
A logical solution to why 12+n is the correct answer to the problem is by subsituting a number to the original expression, lets say we subsitute 4, the expression simplifies to 8. Then we can check for all the other 4 answer choices if their expressions simplify to 8. After deductive reasoning, we are able to pinpoint that 12+n does NOT simplify to 8, which is the solution to the problem.
