Write a program to do the algebraic equation x = a(b+6)/2 multiple times within loops that
vary a and b. The variable a should start at 1 go to 10 and increment by 1. The variable b
should start at 2 and go to 10 and increment by 2. When you display the answer show the formula
in php.
I want you to do this three times: once with a for...next, once with a do...while and once
with a while.
