应该是576,
x+120=3\5[6x-(x+120)]X+120=3/5[6X-(X+120)]应该是576,
x+120=3/5[6x-(x+120)]
5x+600=3[6x-(x+120)]
5x+600=3[6x-x-120]
5x+600=3[5x-120]
5x+600=15x-360
15x-5x=600+360
10x=960
x=96
x+120=3/5(6x-x-120)96
x+120=3/5(5x-120)
x+120=3x-72
3x-x=120+72
2x=192
x=96
x+120=3\5[6x-(x+120)]
2\5(x+120)=3\5×6x
方程式两边×5的2X+240=18X
解得X=15
x+120=3/5(6x-x-120)
x+120=3/30x-5x-600
x+120=10x-5x-600
x-10x+5x=-600-120
-4x=-720
x=180
