3n + 2n = 25 5n = 25 n = 5
25 - 4(4) = 25 - 16 = 9.
It is: 25+(2*13) = 51
If n = 4, then 2n = 8 25 + 8 = 33 25 - 8 = 17 25 x 8 = 200 25/8 = 3.125
2n + 4 = 25
3n + 2n = 25 5n = 25 n = 5
If: 2n = 1 Then: n = 1/2 or 0.5
If: -6n-2n = 16 Then: n = -2
25 - 4(4) = 25 - 16 = 9.
It is: 25+(2*13) = 51
If n = 4, then 2n = 8 25 + 8 = 33 25 - 8 = 17 25 x 8 = 200 25/8 = 3.125
2n plus 7 equals 19 2n equals 12 n equals 6
2n + 4 = 25
-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13
n/27=2n/27*27=2*27n=54
n equals p over 2(like as a division problem. See, you just write n+2n=p then you do this- n+2n=p you take 2 divided by 2 and those cancel ou so if you divide by one so=ide, you have to do it to the other. so you get your answer.
If 'n' is 8, then (2n - 7) is 9 .
