3n + 9 = 3(n + 3)
3 + 3n = 9 + 2n + 4n n = -2
9 - 5n
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
It's an algbraic expession in the form of: 2n+4
2n plus 4 = 2n + 4
18n + 27 or 9(2n + 3)
6n -3=2n+9 6n-2n=9+3 4n=12 n=12/4 n=3
3n + 9 = 3(n + 3)
2n-9=-4
3 + 3n = 9 + 2n + 4n n = -2
9 - 5n
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
It's an algbraic expession in the form of: 2n+4
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
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
