Answer:63
Step-by-step explanation: because if your trying to find x you round to multiple or divide depends on the problem you ask so if you where to multiple like i did you may get the wrong answer but that's where dividing comes in like if i did 7 x 8 which would give me 56 then divide by 2 which would then give me 28 and theres the answer.
Hope i helped i havent done this in a long time so it may be wrong!
