5n + 10 = 10 5n = 10 - 10 5n = 0 n = 0 taylor101119: well i thought it was 5*n+5*2=10 i thought n=1 but i'm pretty sure it's the one ontop^
Whatever your value of n is, you need to multiply it by 5 and then add 2 to get your answer. Below is how to solve it algebraically: 5n+2 = 0 (it needs to be equal to something in order to solve it, so I assumed that it equals zero) 5n = -2 n = -2/5
5n-5, because its the 5 time table (called 5n) minus 5 each time
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+4=0 5n=-4 n= -4/5
5n-2+2=4n 5n=4n n=0
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}

5n - 10 = 0 5n - 10 (+10) = 0 (+10) 5n (/5) = 10 (/5) n = 2
Whatever your value of n is, you need to multiply it by 5 and then add 2 to get your answer. Below is how to solve it algebraically: 5n+2 = 0 (it needs to be equal to something in order to solve it, so I assumed that it equals zero) 5n = -2 n = -2/5
n2 = 6n Rearranging so that all the n's are on the same side gives: n2 - 6n = 0 Factorizing gives: n(n - 6) = 0 The zero product property states that for two numbers to multiply together to gives zero, at least one must be 0. Therefore either n=0 or n - 6 = 0 The two solutions are either n=0, or n=6
n2 = 5n + 24 (subtract 5n and 24 to both sides)n2 - 5n - 24 = 0(n + 3)(n - 8) = 0n + 3 = 0 or n - 8 = 0n = -3 or n = 8
2n+4n-12 = 06n-12+12 = 126n = 121/6(6n = 12)n = 2
