Determine the value of x for the following equation.

3(-9 - 4x) -4 = 8x -9(x + 12)

-77/13

Distribute 3 to the ones in the parenthisis  and do the same to the other side and distribute the negative nine. solve what is left and subtract the two terms and simply solve whats next.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
