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.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
