Answer:
x = 1
Step-by-step explanation:
If x and 2 are in proportion and x+2 and 6 are in proportion, we can make them equal. We can do that by doing:
[tex]\frac{x}{2} = \frac{x+2}{6}[/tex]
After cross-multiplying, we get 2x+4 = 6x.
Subtract 2x on both sides and we get 4 = 4x
divide 4 on both sides and we get x = 1
