f(x)=3^

When solving these types of problem, have a variable set for what you're trying to find.

Let x = the number that when 18 subtracts from 14 and a number will equal 18

Now build the equation.

In the question it says "14 times a number..." which means multiplication.
And also "18 less than" which is subtraction.

And this whole expression is equal to 80.

14x - 18 = 80

Solve for x.

14x - 18 = 80
14x = 98 <--- Add 18 both sides.
x = 7       <--- Divide both sides by 14.

So, x is equal to 7.
