Answer:

12 + 3x = 27

Step-by-step explanation:

statement: 12 larger than 3 times a number is 27

it translates to

12  larger than   3 times a number  = 27

the equal sign replaces the "is"

let the unknown number be x

so...

12  larger than  3*x = 27

the "larger than"  means plus

so  12 + 3x = 27
