To work on this question, you need to move the number between the = sign and the reason for doing so is to find the unknown n. The unknown can be represent by any alphabet from a to z, depending on the question.
The rule is as follows when you move from right to left :
Addition become subtraction
Subtraction become Addition
Multiplication become Division
Division become Multiplication
The same rule apply when you move from left to rigth of the = sign.
Once you memorize the above, solving the problem is easy :
3n+4=7 (bring +4 to right to become -4)
3n=7-4
3n=3 (bring 3 to right multiplication become division)
n=3/3
n-1
