n + 16 = 25 Subtract '16' from both sides. n + 16 - 16 = 25 - 16 Collect terms n = 9
(n+16+16+18)/4 = 17 n+16+16+18 = 17*4 n+50 = 68 n = 68-50 n = 18
16 Fences in the Grand National. Although some are jumped twice, making a race of 30 jumps in total.
16-n
(n - 5) This is how to express 5 less than n mathematically.
(N/8)=(12/16) N= (12*8/16) N=6
There is a total of 16 odd numbered days n the month of December.
25
n(16) + 37 = 53
n + 16 = 9 n + 16 - 16 = 9 -16 (add 16 to both sides, the equation remains same) n + 0 = -7 n = -7
