Answer:
10(n+14)=9N
Step-by-step explanation:
Lets let N represent the number that which we do not know.
We know that 10 is multiplied by the sum of N and 14, so lets write that down:
10(n+14)
We also know that what we just found is equal to 9 multiplied by the same number:
10(n+14)=9N
The variable stays the same throughout the entirety of the equation.
