Solve this problem 9 minus 5n plus 1 equals 15?
9-5n+1 = 15 -5n = 15-9-1 -5n = 5 Divide both sides of the equation by -5 to find the value of n: n = -5
How do you solve 1 minus 7n equals 15 minus 5n?
1 - 7n = 15 - 5n Add 5n to each side: 1 - 7n + 5n = 15 -5n + 5n ie 1 - 2n = 15; subtract 1 from each side: -2n = 14 divide both sides by -2: n = -7
What is 5n plus 1 equals 10 plus 2n?
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
2n plus 3 equals 5n-2?
n=1 2/3
5n plus 3 equals 14-6n what is n?
5n + 3 = 14 - 6n <=> 5n +6n = 14 - 3 <=> 11n = 11 => n = 11/11 = 1
What does n plus 4n-3 equals?
1

-6n + 2 - 5n = -9Combine like terms:-11n + 2 = -9Subtract 2 from each side:-11n = -11Divide both sides by -1:n = 1
What is the 10th term of 5n plus 1?
Tenth term of 5n + 1 = 5*10 + 1 = 51
What is 4 equals 5n plus 6n2?
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}
What is -15 plus 1 equals?
