4 = -5n + 6n2
if you want to solve for n:
6n2 - 5n - 4 = 0
(3n - 4)(2n + 1) = 0
3n - 4 = 0, n = 4/3
2n + 1 = 0, n = -1/2
n = {-1/2, 4/3}

4 = 5n + 6n2 is a quadratic equation.
5n+4=0 5n=-4 n= -4/5
5n+6=(-4) n= (-2)
5n - 4 = 10n + 6-5n = 10n = -2
5n+6=-45n=-10n=-2
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
5n - n = 8 + 4 ie 4n = 12 so n = 3
To solve the equation 5n + 4 = -26, you first isolate the variable n. Subtract 4 from both sides to get 5n = -30. Then, divide by 5 on both sides to find the value of n, which is -6. Therefore, the answer to the equation 5n + 4 = -26 is n = -6.
It is an algebra expression meaning: 5n+4
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
4 over 5n
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
answer is -5.8(-5) + 4 = 5(-5) - 11-40 + 4 = -25 - 11-36 = -36
