(4X-10):(X+10)=7:
问题描述:
(4X-10):(X+10)=7:
答
由题x≠-10,则8(4x-10)=7(x+10)即32x-80=7x+70即25x=150,所以x=6
答
7(x+10)=8(4x-10)
7x+70=32x-80
25x=70+80
x=150/25=6
答
8(4x-10)=7(x+10)
32x-80=7x+70
25x=150
x=150/25=6
答
则8(4X-10)=7(X+10),32X-80=7+70,25X=150,X=6
答
8(4x-10)=7(x+10)
32x-80=7x+70
25x=150
x=6
答
7x+70=32x-80 150=25x x=6
答
(X+10)*7=(4X-10)*8
7X+70=32X-80
70+80=32X-7X
150=25X
X=6
答
7(x+8)=8(4x-10)
7x+56=32x-80
25x=136
x=5.44
