Question

solve for n:6(5n-1)=2(15n-3)

I got 30n-6=30n-6 but I think I was suppose to keep going but don't know how. Do I divide or multiply

Answer 1

At this point, since the two sides of the equation have identical values, the equation is true for ALL values of n.

There is no value of n which makes the equation not true.

If you want to keep going, just do what you usually do. Add 6 to both sides:
30n=30n
subtract 30n from both sides:
0=0

Not much else to do now.
