on left hand side add the3 'n's and add 2 and 4
what do you get?

Answer 4

what is n + n + n?

Answer 5

3n

Answer 6

yep and so LHS = 3n + 6
so we have
3n + 6 = 174

can you continue?

Answer 7

subtract 6 from 174?

well almost - the equation must balance so you subtract 6 from both sides of the =

3n + 6 - 6 = 174 - 6

3n = 168

n = ?
