n = 2
Step-by-step explanation:
1/5 (n+3) = 1/4 (n+2)
First thing to do here is distribute into the parenthesis.
1/5n+3 (1/5) = 1/4n + 2 (1/4)
Now, multiply to simplify the equation.
1/5n + 3/5 = 1/4n + 1/2
Then, subtract 1/2 to both sides.
1/5n + 3/5 = 1/4n + 1/2
-1/2 - 1/2
1/5n + 1/10 = 1/4n
Now, subtract 1/5 to both sides.
1/5n + 1/10 = 1/4n
-1/5n - 1/5n
1/10 = 1/20n
Finally, multiply both sides by the reciprocal of 1/20.
So, multiply by 20/1.
20/1 * 1/10 = 20/1 * 1/20n
This leaves you with n=2.
