The sum of three times a number and seven is greater than twice the number minus four

I'm guessing you want this written as an equation, so here it is.

These can be really tricky at times, so I suggest looking for "clues" in the wording, such as add, subtract, and other things. Also look for what numbers are "paired" together, like in parentheses. Hope that this helps!
