How do you solve 4n minus 7n equals 21?
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
7 times n divided 21 equals 1 what is n?
n = 3Solution:7n/21 = 17n = 1 * 217n = 21n = 21/7n = 3
What is the operation for 3n plus 18 equals 39-4n?
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
What is the answer to 7n equals 91?
7n = 91n = 91÷7n = 13
.5m plus 7n equals 6.4 2m - 7n equals 6?

7n = 91n = 91÷7n = 13
.5m plus 7n equals 6.4 2m - 7n equals 6?
(10, 2)
What is the answer of this questions 7n equals 28?
7n = 28n = 28/7 = 4
How do you work out 7n plus 1 equals 6n plus 8?
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
What is the answer to 5m plus 7n equals 6.4 2-7n equals 6?
2 - 7n = 6therefore 7n = 2 - 6 = -4 and so n = -4/7 Then 5m + 7n = 6.4 becomes 5m - 4 = 6.4 so that 5m = 10.4 and then m = 10.4/5 = 2.08
What is the equation 7n equals 7?
7n = 7 divide by 7 on both sides n = 7
What is 9n-2 equals 7n plus 50?
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
What is 7n²-3n equals 0?
n(7n-3) = 0 n = 0 or n = 3/7
6m plus 5n-4m plus 7n equals?
6m + 5n - 4m + 7n = 2m + 12n
