What is the solution to the proportion #(x+10)/(x-6) = x/(x+4)#?
When solving a proportion problem (like this problem), one approach is to "cross multiply".
The idea is that fraction
So, to solve
We cross multiply, to get:
We are not quite finished. Because we multiplied by expressions involving a variable, we need to.make sure we did not multiply by
As a final check make sure that
