hi i would really appreciate some help solving this question simultaneously:

Find A and B such that

x-11/(x+3)(2x-1)= A/x+3 + B/2x-1

Multiply both sides by (x+3)(2x-1) to get rid of the fractions.

We end up with this:

(x-11) = A(2x-1) + B(x+3)

You can solve for A and B more easily now.

I hope this helps and is what the problem was asking.

how can estimation help you deside if the exact product for 7 times $74.65 is greater or less than $600?
