Answer:

Step-by-step explanation:

AC = 64
AB = 7x + 8
BC = 3x + 6

<u>Since AC = AB + BC</u>

7x + 8 + 3x + 6 = 64
10x + 14 = 64
10x = 50
x = 50/10
x = 5

------------------

BC = 3x + 6 = 3*5 + 6 = 21

Solve for x. <br><br> a²x+(a-8)=(a+8)x

Sergio [31]

$a^2x+(a-8)=(a+8)x\\\\(a+8)x=a^2x+(a-8)\ \ \ \ |subtract\ a^2x\ from\ both\ sides\\\\(a+8)x-a^2x=a-8\\\\(a+8-a^2)x=a-8\ \ \ \ |divide\ both\ sides\ by\ (a+8-a^2)\\\\\huge\boxed{x=\frac{a-8}{a+8-a^2}}\to\huge\boxed{x=\frac{8-x}{a^2-a-8}}$
