Y = 3/8(x + 4)....multiply both sides by 8/3, eliminating the 3/8 o the right 8/3y = x + 4....now subtract 4 from both sides 8/3y - 4 = x <==
n = m^2 - (n + 3) n = m^2 -n - 3...add n to both sides n + n = m^2 - 3 2n = m^2 - 3...add 3 to both sides 2n + 3 = m^2...take sqrt of both sides, eliminating the ^2 sqrt (2n + 3) = m or m = - sqrt (2n + 3) <==
