0.35x0.3+0.35x0.4=2x+2,解得x=480.35X乘以0.3+0.35X乘以0.4=2X+2,解得X=480.35x0.3+0.35x0.4=2x+2,解得x=480.35X乘以0.

0.35x0.3+0.35x0.4=2x+2,解得x=480.35X乘以0.3+0.35X乘以0.4=2X+2,解得X=48
0.35x0.3+0.35x0.4=2x+2,解得x=48
0.35X乘以0.3+0.35X乘以0.4=2X+2,解得X=48

0.35x0.3+0.35x0.4=2x+2,解得x=480.35X乘以0.3+0.35X乘以0.4=2X+2,解得X=48
0.35x0.3+0.35x0.4=2x+2 这里面出现的是三个x是吧（我可不想把它当作乘号）如果是：那么答案是错的是乘号也是错的,答案应该是：x=-0.8775 （前面两个x是乘号的情况）没有根据地答案不用相信.
