Answer:
Step 1: Shift the 2 on the other side, this changes its function. So addition becomes subtraction.
3x+2=14 becomes, 3x=14-2
Step 2: subtract the two.
3x=12
Step 3: Move 3 on the other side, and it reverts the function again. So multiplication becomes division.
3x=12 becomes, x=12/3
Step 4: Divide the two digits and you'll get your answer.
x=4
Thus the answer is 4.
