Since you did not provide the question, I would have to make a smart guess. The logical question would be to find the value of x. We are given a verbal expression here. If you turn it into an algebraic expression, that would be written as:
x - 7 = 5
The statement 'x less 7' means that x is subtracted with 7, then the difference is equal to 5. Since there is one unknown and one independent equation, we can solve the equation. Do this by transposing algebraic terms. Isolate all the constants to the write, and all the variables to the left. When you transpose terms, take the inverse sign with them. If - 7 is transferred to the other side, that would now be +7.
x = 7 + 5
x = 12
Therefore, the value of x in this equation is equal to 12.
