2\/3x加1\/2x等于42 求个.未知数
回答:7\/6x=42 x=36
2\/3X+1\/2X=42
4\/6x+3\/6x=42 x=42÷7\/6 x=36
2\/3x十1\/2x=42求未知数
答案是36。粗暴的解释一下哦,毕业好久了。(2\/3+1\/2)x=42。把2\/3和1\/2变成4\/6和3\/6,4\/6+3\/6=7\/6。42÷7\/6。除的话要把它分子分母倒过来,42x6\/7=36
2\/3x+1\/2x=42解方程要过程?
(2\/3+1\/2)x=42,7\/6x=42,x等于42÷7\/6,x=42×6\/7,x等于36。
2\/3X+1\/2X=42求解
2\/3X+1\/2X=42 两边×6 4x+3x=252 7x=252 x=252÷7 x=36 祝学习进步
2\/3x+1\/2x=42

解方程;2\/3X+1\/2X=42?
7\/6x=42 x=42×6\/7 x=36
2\/3x加1\/2x等于42
X=36
2\/3X加1\/2X=42 7.5X除以0.3=10 1\/4:X=1\/2:1\/6
如图。
三分之二X加二分之一X等于四十二?
(2 x)\/3 + x\/2 = 42 x = 36
