If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
m=16, n=2
n = -8
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
4n/7 + 8 = 20 subtract 8 from each side: 4n/7 = 12 multiply each side by 7: 4n = 84 n = 21
8 x 0 =4n 0 = 4n 0=n
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
8+4n=-4 algebra gives us 4n=-12 n=-3
m=16, n=2
4n-8
n = -8
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
4n/7 + 8 = 20 subtract 8 from each side: 4n/7 = 12 multiply each side by 7: 4n = 84 n = 21
The answer to that question is 2 times a -4 equals -8
8 = 4n n = 2
2 to the 3rd power equals 8, because 2 times 2 times 2 equals 8.
