各位知識朋友 , 入黎幫我手 ar !!! 我有幾條數學問題唔識 , 幫手解答 ar( 數學F.1 )!!!!!!!!!!!!!!!( 要步驟 ) 1. 14 - 2(4x - 2)∕3 = 2
最佳解答:
14 - 2(4x - 2)∕3 = 2 2(4x - 2)∕3 =14-2 2(4x - 2)∕3=12 2(4x - 2)=12x3 2(4x - 2)=36 (4x - 2)=36/2 4x - 2=18 4x=18+2 4x=20 x=20/4 x=5 所以x係等於5 詳唔詳細?
其他解答:
14 - 2(4x - 2)∕3 = 2 14 - 2 = 2 (4x - 2)∕3 12 = 8x - 4∕3 12 x3=8x-4 36+4=8x 40/8=x x=5 希望可以幫到你(^_^)|||||14-2(4X-2) / 3 = 2 14 - 2(4x-2) / 3 = 2 左 右 兩 邊 同 時 乖 3 42 - 2(4x - 2) = 6 42 - 8X + 4 = 6 46 - 8X = 6 46- 6 = 8X 40 = 8X X = 8|||||14 - 2(4x - 2)∕3 = 2 14 - 2 = 2 (4x - 2)∕3 12 = 8x - 4∕3 12 x3=8x-4 36+4=8x 40/8=x x=5|||||[14 - 2(4x - 2)]∕3 = 2 ? ans:14 - 2(4x - 2)= 6 - 2(4x - 2)= -8 2(4x - 2)= 8 8x-4=8 8x=12 x=3/2 14 - [2(4x - 2)∕3 ]= 2 ?
