(4n + 1)*(2n + 6) = 8n2 + 26n + 6
2n plus 7 equals 19 2n equals 12 n equals 6
Given that 2n = 6 + n, subtract n from each side and n = 6
6=(1-2n)+5 6-5=(1-2n)+5-5 1=1-2n 1-1=1-1-2n 0=-2n 0/-2=-2n/-2 0=n
(2n - 3)(n - 6)
(4n + 1)*(2n + 6) = 8n2 + 26n + 6
Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
2n plus 7 equals 19 2n equals 12 n equals 6
Given that 2n = 6 + n, subtract n from each side and n = 6
6=(1-2n)+5 6-5=(1-2n)+5-5 1=1-2n 1-1=1-1-2n 0=-2n 0/-2=-2n/-2 0=n
the answer is 0
n = 1
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
-6
Well, if 6 equals 1 plus five, the 2n you put in the middle must be nothing. Think. n=0 Sorry If it's not right
-2n+21 or 21-2n (if you are not comfortable with leading negative signs).
