解方程:(48x+36)(57x+39)-(57x+45)(48x+36)=0
解方程:(48x+36)(57x+39)-(57x+45)(48x+36)=0

解方程:(48x+36)(57x+39)-(57x+45)(48x+36)=0

-3/4

(48x+36)(57x+39)-(57x+45)(48x+36)=0
(48x+36)(57x+39-57x-45)=0
-6(48x+36)=0
所以48x+36=0
所以x=-3/4
如果不懂,请追问,祝学习愉快!

全是0

(48x+36)(57x+39-(57x+45))=0
48x+36-6=0
x=-5/8

(48x十36).(一6)=0,求得:x=一0.75
