Answer:

x = 20

Explanation:

Hey there!

To solve this equation, we will use a method called cross multiplying

This is where you take the LHS denominator and multiply it with the RHS numerator

And you take the RHS denominator and multiply it with the LHS numerator:


(11)/(13)=(22)/((x+6)) \\ \\ 11x+66=286 \\\\11x=220\\\\x=(220)/(11) \\\\x=20
