-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
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
You cannot, because there is no solution.5 is not a factor of 144. Therefore 5 is not a factor of (3n + 9)! / (2n + 4)!Therefore (3n + 9) - (2n + 4) < 5n < 0.Also, 2n + 4 must be non-negative.ie 2n >= -4 or n >= -2.So the only possible values for n are -1 and -2.But n = -1 gives 6!/2! = 720/2 = 360while n = -2 gives 3!/0! = 6
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.
