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

What is the answer to 3 plus 3n equals 9 plus 2n plus 4n?
3 + 3n = 9 + 2n + 4n n = -2
41 minus 2n equals 2 plus n?
41 - 2n = 2 + n Add 2n to each side: 41 = 2 + 3n Subtract 2 from each side: 39 = 3n Divide each side by 3: 13 = n
What is 3n plus 3 equals n plus 7?
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
6n-2n plus 2 equals n-11?
6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333
What is (n-8)-(-2n plus 2)?
It is an expression that can be simplified to: 3n-10
What is the answer to 3 plus 3n equals 9 plus 2n plus 4n?
3 + 3n = 9 + 2n + 4n n = -2
What is 3n plus 5 equals 2n plus 7?
3n+5=2n+7 subtract 2n on both sides. n+5=7 subtract 5 to the other side. n=2 the answer to n is 2. Hoped that helped. (:
41 minus 2n equals 2 plus n?
41 - 2n = 2 + n Add 2n to each side: 41 = 2 + 3n Subtract 2 from each side: 39 = 3n Divide each side by 3: 13 = n
What is 3n plus 3 equals n plus 7?
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
What is n in 5n plus 12 equals 3n?
5n + 12 = 3n Try to get all expressions with n on the left side 5n + 12 - 3n = 3n - 3n 2n + 12 = 0 Try to get rid of 12 on the left side 2n + 12 - 12 = -12 2n = -12 n = -12/2 = -6
6n-2n plus 2 equals n-11?
6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333
What is the perimeter of a rectangle with width 3n plus 2 and length n-1?
perimeter equals 2 times width plus 2 times length so, perimeter equals 2(3n+2)+2(n-1) = 6n+6+2n-2 = 8n+4.
How would you solve 3n-2n?
3n - 2n = n 3n - 2n = (3 - 2)n = 1n = n
What is (n-8)-(-2n plus 2)?
It is an expression that can be simplified to: 3n-10
How do i Solve for n 2n-3n equals one third n plus 14?
The question seems ambigous, but I will consider n 2n to be solving for n:2n - 3n = n/3 + 14-n = n/3 + 14-3n = n + 42-4n = 42Thus, the solution is n = -42/4 = -21/2 = -10.5.
How do you Simplify the expression n plus 2n plus 2?
Combine like terms to give 3n + 2
How do you simplify the expression -5n --3n?
-2
