Answer:
It should be 4. The ratio that AC is equal to DE at should be equal to the ratio of BE to BC. If you want an explanation I'd be happy to add one!
Equation: <span> 840+17x=760+22x
Solve for x x=16 see proof.
17 x + 840 = 22 x + 760
Subtract 22 x from both sides:
(17 x - 22 x) + 840 = (22 x - 22 x) + 760
17 x - 22 x = -5 x:
-5 x + 840 = (22 x - 22 x) + 760
22 x - 22 x = 0:
840 - 5 x = 760
Subtract 840 from both sides:
(840 - 840) - 5 x = 760 - 840
840 - 840 = 0:
-5 x = 760 - 840
760 - 840 = -80:
-5 x = -80
Divide both sides of -5 x = -80 by -5:
(-5 x)/(-5) = (-80)/(-5)
(-5)/(-5) = 1:
x = (-80)/(-5)
The gcd of -80 and -5 is -5, so (-80)/(-5) = (-5×16)/(-5×1) = (-5)/(-5)×16 = 16:
Answer: x = 16</span>
