Re: Algebra Help

Hi;

Determine the value of 4(x + 4)-3 when x=7.

Wherever you see an x you replace it with a 7.

So 4(x + 4) - 3 becomes 4(7 + 4) - 3.

4(7 + 4) - 3 becomes 4(11) - 3.

4(11) - 3 becomes 44 - 3 = 41 which is the answer.

Welcome to the forum.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
