15 + n = 24 (subtract 15 from both sides) n = 9
It is a linear equation in one variable, n.
-24
for n=4: (4 x 5) + 4 = 24
-24
3n=24 n=8
It is a simple linear equation in a single variable, n. And, in case you are wondering, n = 12.
13n-12n=14+10 13n-12n=1n 1n=n n=14+10 14+10=24 n=24 so the answer is n=24
The answer to -2(4+3n)=24 is:-5.33
n = 8
2 plus n is the true one, but 1 plus n is not?
4n + 24 = 484n + 24 - 24 = 48 - 244n + 24 - 24 = 48 - 244n = 48 - 244n = 244n/4 = 24/44n/4 = 24/4n = 24/4n = 6
