(2.46--0.26)x(?)+12.5除以0.5=60.2
(2.46--0.26)x(?)+12.5除以0.5=60.2
解方程:x除以0.05除以2=(4500-x)除以0.02除以4
问:解方程:(0.3X-1)除以0.02-(4X-8)除以0.5=1
X除以(X-80)=3
解方程 X除以(X-2) + (X-9)除以(X-7) = (X+1)除以(X-1) +(X-8)除以(X-6)
解方程;(1)20%x除以(10+x)=16% (2) x-1除以0.3-x+2除以0.5=1.2
(3.8-x)除以7=3除以28
1除以(0.5X-1)=6 解方程
(2/3)除以x+(1/3)除以(x-5)=1除以(x-3) ,
(X除以10+X除以8)乘以4+5000=X
x除以(x-3) -2=-3除以(3-x)
1-(0.7+3x)除以0.8=(0.3x-1)除以0.4-x
