How do you solve 4n plus 13 equals n minus 8?
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
7 minus 2n equals 8n minus negative4n then what does N equal?
n=10/7. i did this one mentally. but are you sure its 8n minus negative 4n or is it 8n minus 4n? 8n- -4n does not equal 8n-4n 8n- -4n is the same as 8n+4n
4n divided by 7 plus 8 equals 20 solve for n?
4n/7 + 8 = 20 subtract 8 from each side: 4n/7 = 12 multiply each side by 7: 4n = 84 n = 21
What is 4n minus 2n equals 84?
4n - 2n = 84 2n = 84 n = 42
How do you Solve 5n-2 plus 2 equals 4n?
5n-2+2=4n 5n=4n n=0
How do you solve 4n plus 13 equals n minus 8?
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
7 minus 2n equals 8n minus negative4n then what does N equal?
n=10/7. i did this one mentally. but are you sure its 8n minus negative 4n or is it 8n minus 4n? 8n- -4n does not equal 8n-4n 8n- -4n is the same as 8n+4n

4n/7 + 8 = 20 subtract 8 from each side: 4n/7 = 12 multiply each side by 7: 4n = 84 n = 21
What is 4n minus 2n equals 84?
4n - 2n = 84 2n = 84 n = 42
How do you Solve 5n-2 plus 2 equals 4n?
5n-2+2=4n 5n=4n n=0
Solve for n 17 equals 4n - 3?
The answer is n = 5.
What is 4n plus 11 minus 7n equals negative 13?
-2.18
Solve n for 12 plus 4n equals 2n?
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
How can you solve m-4n equals 8?
m=16, n=2
What is 4n minus 2n equals 18?
4n - 2n = 18 Therefore, 2n = 18 Therefore, n = 18/2 = 9
5n minus 11 equals 4n plus 20 What is n?
In the equation 5n-11=4n+20, n is equal to 31.
Solve for n 4n plus 3 equals 19?
4n + 3 = 19Subtract 3 from each side:4n = 16Divide each side by 4:n = 4
