(4x-3y)-[-(3y-x)+(x-y)]-5x(4x-3y)-[-(3y-x)+(x-y)]-5x(4x-3y)-[-(3y-x)+(x-y)]-5x(4x-3y)-[-(3y-x)+(x-y)

(4x-3y)-[-(3y-x)+(x-y)]-5x
(4x-3y)-[-(3y-x)+(x-y)]-5x

(4x-3y)-[-(3y-x)+(x-y)]-5x
(4x-3y)-[-(3y-x)+(x-y)]-5x
解:原式=4x-3y-[-3y+x+x-y]-5x
.=4x-3y-(2x-4y)-5x
.=4x-3y-2x+4y-5x
.=y-3x
如有不懂.百度HI我.祝愉快

(4x-3y)-[-(3y-x)+(x-y)]-5x
解:原式=4x-3y-[-3y+x+x-y]-5x
=4x-3y-(2x-4y)-5x
=4x-3y-2x+4y-5x
=y-3x

(4x-3y)-[-(3y-x)+(x-y)]-5x
解:原式=4x-3y-[-3y+x+x-y]-5x
=4x-3y-(2x-4y)-5x
=4x-3y-2x+4y-5x
=y-3x
