It is impossible to solve for n if there's nothing to equate it with. No could be any number each except for -4. All we know is n = n

12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
It is an expression that can be simplified to -4n-1
4n+13=1 -13 -134n=-12/4 /4n=-3
4n + 1 = 12 + 5n First, let's get all n terms on one side and all non-n terms on the other side. Start off by subtracting 4n from each side. 1 = 12 + n Now subtract 12 from each side. -11 = n
8 = 4n n = 2
