4n + 5
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
It is a linear equation in one unknown variable, n. Its solution is n = 1
555 plus 5 plus 556 is equal to 1,116
4b plus 7b plus 5 will equal 11b plus 5. When you have two variables that are the same you can add the two numbers with the variables remaining the same.
4n + 5
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5

12 times 5 plus 25 is equal to 85.
yes they are
It is 12n2 + 3n - 58
The answer depends on the value of x.
Starting from 1, your get: [4n + 5] = 9, 13, 17, 21, 25 Basically you find the first one and add 4 each time.
for n=4: (4 x 5) + 4 = 24
If you mean: 4n^2-60n+200 = 0 then the solutions are n = 10 or n = 5
It can be (for x = -2.5) but not for any other value of x.
