Question 241114
Hello, 
The fastest way is cross multiply so it looks like this:
 2(x-2)=4(x+4)  Now distribute to look like this:
2x-4=4x+16  Add 4 to both sides and subtract 4x from both sides will give us:
-2x=20  Divide by -2
x=-10  Now let's put this into the original proportion and is should work out fine.
