b = 38

c = 1 for every 6

i have no clue at all sorry

step-by-step explanation:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
