Ok so in order to solve this, we multiply both sides by 56(10+x). This results in two cancellations. On the left-hand side it becomes 56×10 and on the right-hand side it becomes 35(10+x). Simplifyingnthings we get 350 + 35x = 560. Subtract 350 from both sides and we get 35x=210. divide by 35 and you get x = 6.
