In the equation 5n-11=4n+20, n is equal to 31.
4/9 = 20/n 4n = 9(20) 4n = 180 n = 45
4n/7 + 8 = 20 subtract 8 from each side: 4n/7 = 12 multiply each side by 7: 4n = 84 n = 21
4n -14 = 22 4n = 22+14 4n = 36 n = 9
Move the 2n over the equals sign. Become 4n (as 6n-2n= 4n) and then if 4n=16 then n=4.
