x = the number

+2+%2B+%28x%2F2%29+=+x+%2B+1+ --->> +highlight%28+x+=+2+%29+


-----------
Showing the steps:
+2+%2B+%28x%2F2%29+=+x+%2B+1+

Subtract x/2 from each side:
+2+=+x%2F2+%2B+1+

Subtract 1 from each side:
+1+=+x%2F2+

Multiply each side by 2:
+2+=+x+

... which may also be written +x+=+2+



Check:  2 + (2/2) = 2 + 1 = 3    <<< 2 + (1/2)*number

         and 2 + 1 = 3  (ok)     <<<  the number + 1
