You can put this solution on YOUR website! this is how you solve this:
4n-15=11n-1
4n-15+15=11n-1+15 you add 15 to both sides.
4n=11n+14
4n-11n=11n-11n+14 You subtract -11 from both sides.
-7n=+14
-7n/-7=+14/-7 You divide -7 and +14 by -7 and reduce
n=-2 By reducing you get - 2.
Check.
4n-15
4(-2)-15
-8-15
-23 hence left side = right side
11n-1
11(-2)-1
-22-1
-23
