5n%2B4-8n=13 Start with the given equation.


-3n%2B4=13 Combine like terms on the left side.


-3n=13-4 Subtract 4 from both sides.


-3n=9 Combine like terms on the right side.


n=%289%29%2F%28-3%29 Divide both sides by -3 to isolate n.


n=-3 Reduce.

Starting with,
5n+4-8n=13
Combine like terms
-3n + 4 = 13
-3n + 4 - 4 = 13 - 4
-3n = 9
-3n/-3 = 9/-3
n = -3
Proof
5(-3) + 4 - 8(-3)
-15 + 4 + 24
-15 + 28
13
