The equation is: #3N+1=7#

The solution is: #2#

You say: "one more than three times a number is 7".

So we start with a number #N#.

Then we multiply it by #3# to get: #3N#

Then we increase it by #1# to get: #3N+1#

And we equal all of that to #7#: #3N+1=7to# [ANS}

Solving: #3N+1=7#

#3N+1-1=7-1#

#3N=6#

#N=6/3#

N=2

"one more than three times a number is 7".

"one more than three times N is 7".

"one more than three times #2# is #7"#.
