Subtract 2n from each side: 3n - 9 = 6 Add 9 to each side: 3n = 15 Divide both sides by 3: n = 5 Therefore, n = 5

first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
2n + 5 = 25 < ---------------- Write the Equation 2n = 20
6=(1-2n)+5 6-5=(1-2n)+5-5 1=1-2n 1-1=1-1-2n 0=-2n 0/-2=-2n/-2 0=n
3n + 2n = 25 5n = 25 n = 5
2n+5 = 3n 5 = 3n-2n 5 = 1n check 2n+5 = 3n 2x5+5 = 3x5 10+5 = 15 15 = 15
It is 12n2 + 3n - 58
Subtract 2n from each side: 3n - 9 = 6 Add 9 to each side: 3n = 15 Divide both sides by 3: n = 5 Therefore, n = 5
3n + 9 = 3(n + 3)
15/6n + 6/6n = 21/6n = 7/2n

Combine like terms to give 3n + 2
first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
5-2=3n=3
5n - 9 = 2n + 6 : Add 9 to both sides 5n = 2n + 15 : Subtract 2n from both sides 3n = 15 : Divide both sides by 3 n = 5
2n+3n+4 = -2 //combine the like terms(2n and 3n) 5n+4=-2 //now subtract four from both sides of the equation in order to isolate n 5n=-6 //lastly divide the -6 by 5 n = (-6/5)<== improper fraction n = (-1 1/6)<== mixed number/proper fraction Should be n = (-1 1/5) if you want to end up with a number proper fraction or if not n=-1.2
