Start by distributing -8 to (8-3n) and -5 to (n+1). The equation becomes:
-64+24n-5n-5=4n-1-8
Next, you can simplify both sides of the equation. It will look like:
-69-19n=4n-9
Next, add 19n to both sides so you isolate the variable on one side of the equation. You will get:
-69=23n-9
Now, you can proceed to solve this like any other two-step equation. Add 9 to both sides:
-78=23n
Divide both sides by 23:
-3.3913=n
Hope this helps!
