When solving x%2F2=6, you multiply both sides by 2 to isolate x. So

x%2F2=6

2%28x%2F2%29=2%2A6

x=12


=======================================================

Yes %282%2F7%29x=4 and x+=+14 are equivalent because if you solve for x in the first equation, you get the following


%282%2F7%29x=4

2x=4%2A7 Multiply both sides by 7.

2x=28

x=28%2F2 Divide both sides by 2 to isolate x.

x=14
