A coming of age story about two childhood best friends who grow apart
<u>Answer:</u>
x =
& 3
<u>Step-by-step explanation:</u>
= 
Cross multiply:
=
⇒ (8x)(7x) = (5x+3)(10x-2)
Simplify both sides:
(8x)(7x) = (5x+3)(10x-2) ⇒ 56x² = 50x²+20x-6
Set equation equal to 0:
56x² = 50x²+20x-6 ⇒ 0 = -6x²+20x-6
Factor the trinomial:
0 = -6x²+20x-6 = (-6x+2)(x-3)
Solve for X:
-6x+2 = 0
-6x = -2
x =
;
x-3 = 0
x = 3;
x =
, 3
