I don't get 7/8n-3=5/8n+12??
2 answers:
Hey there, subtract 5/8n from both sides, 7/8n-3-5/8n+12-5/8n=1/4n-3=12, add 3 to both sides, 1/4n-3+3=12+3=1/4n=15, multiply both sides by 4, 4*1/4n=4*15, 4*15=60. So, n=60
7/8n - 3 = 5/8n + 12 (7n)/8 - 3 = (5n)/8 + 12 7n - 24 = 5n + 96 7n = 5n + 96 + 24 7n = 5n + 120 7n - 5n = 120 2n = 120 n = 120/2 n = 60 The answer is: n = 60
