So I don't know how to do this problem: 2=5+n/10
Karin from Algebra Class Says:
With this equation, I am going to assume that you meant to put parenthesis around the 5+n meaning that the fraction is 5+n in the numerator and 10 in the denominator.
5+n = 2
Step 1: Get rid of the fraction, or the 10 in the denominator by multiplying every term by 10.
(10)5+n = 2(10)
For the first term (5+n/10) the 10 in the numerator and denominator cancel or simplify and we are left with 5+n. On the right side, 2 times 10 equals 20.
We now have:
5+n = 20
Step 2: Subtract 5 from both sides.
5-5+n = 20-5
n = 15
The variable n = 15 is the solution.
Step 3: Check your solution.
2 = (5+15)/10
2 = 20/10
The solution is correct.
I hope this helps.
