a. if M=15，find the value of E 你既意思係：(1) M=60-E/3 15=60-E/3 15+E/3=60 E/3=60-15 E=(60-15)*3 =135 定係：(2) M=(60-E)/3 15=(60-E)/3 15*3=60-E 45=60-E -15=-E E=15 b. find the value of E such that the corresponding value of M is twice the value of M given in a 佢係問，如果Ｍ=15*2 (M is twice the value of M given in a)，Ｅ=咩？ (1) 2M=60-E/3 15*2=60-E/3 30=60-E/3 30+E/3=60 E/3=30 E=90 OR (2) 2M=(60-E)/3 15*2=(60-E)/3 30=(60-E)/3 30*3=60-E 90=60-E 30=-E E=-30 2012-11-27 22:07:40 補充： 應該係第二個答案^^
