5-(2x+3)-3÷4(x-2)-1÷2(2x+3)
5-(2x+3)-3÷4(x-2)-1÷2(2x+3)
5-(2x+3)-3÷4(x-2)-1÷2(2x+3)
5-(2x+3)-3÷4(x-2)-1÷2(2x+3)
=5-2x-3-3/4x+3/2-x+3/2
=5-3+3/2+3/2-2x-3/4x-x
=2+3-15/4x
=5-15/4x
5-(2x+3)-3÷4(x-2)-1÷2(2x+3)
= 5-2x-3-0.75x-1.5-x+4.5
=5-0.25x
对面是几?5-0.25x=?
拜托,你是要化简吗?如果求是得不出x的。
5-(2x+3)-3÷4(x-2)-1÷2(2x+3)=
5-2x+3-0.75x+1.5-x-1.5=
-3x+7.25
竖式麻烦,懒得弄了
