Answer
10 is an answer to the equation.
Work Step by Step
Solve for n in the equation.
n+20 = 4n -10
n + 20 = 4n - 10
+10 +10
n+30=4n
-n -n
30=3n
Divide both sides by 3 to isolate the variable.
30/3 = 3n/3
10 = n
The set of potential answers includes 10. This is the answer. You can also plug in 0 and 20 to double-check. Of the 3 solutions, only 10 satisfies the equation.
