Answer:
(x-7)/(x+2)
Step-by-step explanation:
(x-7)(x+7)/(x+7)(x+2)
(x-7)/(x+2)
c/7 = 6 1/7 ⇒ c = 43 ⇒ 43/7 = 6 1/7
Convert mixed fraction into a simple fraction
6 1/7 ⇒ (6 * 7 + 1)/7 = 43/7
c/7 = 43/7
proportionality:
a/b = c/d where cross products are equal : ad = bc
a = c
b = 7
c = 43
d = 7
<span>ad = bc ⇒ c7 = 7*43 ⇒ c7 = 301 ⇒ 7c/7 = 301/7 ⇒ c = 43</span>
