8(x-0.5)=6(x+0.5)
解方程:x+3x=148 15x-8x=5.6 6x-x=96 2除以x=0.5 3x+3=84 6x=14x=82-5
4a+3a-2a=?2b-b+0.5b=?10x-(7x+x)=?6x-1.5x=?8x+4x-8x=?7.5x-x+2
已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
6X-(360X-0.5X)=2×(360X-0.5X)
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
8x-0.5x=0.5x-21怎么算
1. x+0.5x=6 4x+16=40 x/5=32% x-4/9x=10/21 x-1/8x=5/8 7x÷2=2.
4X+0.5X=13.5X
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
4(x-3)=2x 8x+0.5=4x+4.5 4x+20=6x-10 解方程
5*(x-2)=4*(x+3) 2x+(50-x)*4=140 3x-(8-x)=20*4 200x=(x-0.5)*2
2.5x-0.5×8=6,x=?
