Hard to do when there's no expression provided :-)

whpalmer4 · Answer

Okay, write "6" wherever you "b" and "5" wherever you see "a" in the expression.  What does that equal?

whpalmer4 · Answer

wherever you "b" -> wherever you see "b"

substitute 5 in for a and 6 in for b.
b + 9a = 6 + 9(5) = your answer

Think of it like you are following a recipe... "I need 3 of these, and 4 of those, and 1 of these..."

No, you want to collapse it down as far as you can, which would be  to 51 in this case.
