7(x + 1) = 63 
That is the equations of the words above. The simplified version is:

7(x + 1) = 63
7x + 7 = 63 (multiplied 7 by x and the 7 by 1)
      - 7    -7
-----------------
7x = 63
----   ----   (divide by seven to leave the variable, in this case the letter x, alone)
7       7
x = 9  (63/7 = 9)
