#11=n#

Some tricks:

Think of the words as math symbols:

#"is"##=>=#
#"more than"##=>+#
#"times"##=>*#
We let #n# equal the number.

We have:

#"45 is 12 more than 3 times a number."# Replace words with signs.

#45=12+3*n#

Subtract twelve on both sides.

#=>33=3*n# divide both sides by #3#.

#=>11=n# That is the answer!
