That factors to (2n + 1)(n + 2)
first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
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
5n + 6n - 2n
n - 16 = 2n + 12 + 3nCombine the 'n' terms on the right side:n - 16 = 5n + 12Subtract 'n' from each side:-16 = 4n + 12Subtract 12 from each side:-28 = 4nDivide each side by 4:-7 = n
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
9 - 5n
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
1 - 7n = 15 - 5n Add 5n to each side: 1 - 7n + 5n = 15 -5n + 5n ie 1 - 2n = 15; subtract 1 from each side: -2n = 14 divide both sides by -2: n = -7
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
n=1 2/3
3n + 2n = 25 5n = 25 n = 5
5n = 2n + 3n .
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
