Answer:
n=15
Step-by-step explanation:
5(n+1)=2n+20
U start by expanding the first term which will give you 5n+5
Then after that u collect like terms giving u
5n-2n=20-5
Finally u evaluate it giving u
n=15
First we have to expand 5(n + 1)
Meaning we have to multiply everything in the bracket by 5. That would mean 5n + 5.
Now we have 5n + 5 = 2n +20
Subtract 2n from both sides to get rid of the 2n on the right
So you will have 3n + 5 = 20
Now subtract 5 from both sides to get rid of the 5 on the left.
So you will have 3n = 15
Divide both sides by 3 to get n = 5
Answer is n = 5
Meaning we have to multiply everything in the bracket by 5. That would mean 5n + 5.
Now we have 5n + 5 = 2n +20
Subtract 2n from both sides to get rid of the 2n on the right

Now subtract 5 from both sides to get rid of the 5 on the left.
So you will have 3n = 15
Divide both sides by 3 to get n = 5
Answer is n = 5
