Answer:

n = 1

Step-by-step explanation:

Add 20 to both sides, obtaining

n = 4 - 3n

Next, add 3n to both sides:

4n = 4

Finally, solve for n by dividing both sides by 4:

n = 1
Answer: n = 6




Step-by-Step Explanation:

•Solve:

n-20 = 4-3n

•Add 3n on both sides:

n-20 = 4-3n
+3 +3


4n-20 = 4

• Add 20 both sides:

4n-20 = 4
+20 +20
———————
4n = 24

• Then you divide 24 by 4:

4n = 24

4 4

• Result:

n = 6
