Stan worked 4 years less than Marco.This year Stan has worked 29 years.If b is how long Marco worked, the equation b - 4 = 29 re
MA_775_DIABLO [31]

Answer:

Add 4 on both sides.

In the equation there is a -4.

If -4+4=0, that is how you would get rid of the -4.

But, you need to add 4 to 29 to really get rid of the -4.

So, 29+4 is 33.

b=33
