2n plus 7 equals 19 2n equals 12 n equals 6
0
2n + 5 = 25 < ---------------- Write the Equation 2n = 20
Given that 2n = 6 + n, subtract n from each side and n = 6
2n+2n equals 4n
It can't be simplified any further so it is:2m + 2n + p
n= -2
Yes.
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.
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
2n plus 7 equals 19 2n equals 12 n equals 6
2(2n + 5) = 12 2n + 5 = 6 2n = 1 n = 1/2
Solve for n. 2n+3=0 2n=-3 n=-3/2
n + 2 = 5, solve for n.n = 5 - 2n = 3
Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.
It can be simplified to: 9m-2n
