Question

The product of 7 and a number, increased by 3, is equal to twice the number, subtracted from 39. Find the number.

Answer 1

It's just an equation, the number you're looking for is X, and then turn the words into an solvable equation with respect to X.

7X + 3 = 39 - 2X
9X = 39 -3 = 36
X = 4
