Answer :
9n-2=7n+50
add 2 to both sides
9n=7n+52
subtract 7n from both sides
2n=52
divide both sides by 2
n=26
add 2 to both sides
9n=7n+52
subtract 7n from both sides
2n=52
divide both sides by 2
n=26
2n - 2 = 50 <--- subtract 7n from 9n
2n = 52 <---- add 2 to 50
n = 26 <----- divide 52 by 2
n = 26 <----- your answer
2n = 52 <---- add 2 to 50
n = 26 <----- divide 52 by 2
n = 26 <----- your answer
