+69 Let y = (x-3)/((x+7)
Then this equation can be expressed in the form (x + a)(y + b) = c for some constants a, b, and c . Enter your answer in the form " a, b, c".
Thanks in advance.
+37155 xy + 7y = x-3 after multiplying both sides by (x+7)
x - xy - 7y -3 = 0
(x+7)(-y+1) = 3 +7 multiply both sides by -1
(x+7)(y-1) = - 10
take it from here !
