Answer:
n=13
Explanation:
7n-18=5n+6 move variables to 1 side
-5 -5 (in this case subtract 5 on both sides of the equal sign)
2n-18= 6 now you want to get the variable alone
+18 +18 (in this case add 18 on both sides of the equal sign)
2n=26 now you want to get the variable (N) by itself
/2 /2 ( so divide 2 on both sides of the equal sign )
n=13
