(x+16)*6=120
4+6X(3x-2)=16x 怎么解方程?注备:X=乘 x=x
解方程:2x(x-2)-6x(x-1)=4x(1-x)+16.
8x-16=32 x-8分之5x=32 7x-(6+3x)=30 4x+(5-3x)=19
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
3/x-1=4/x 6/x+1=x+5/x(x+1)
(x+16)*6=120
问几道解方程x/6-x=(x-3)/6x-1=1/2x+1/4x+1/8x+1/16x+1/32x77/x=2.5*77
解方程(1)x²-6x-6=0 (2)x²-2x-1=0 (3)x(x+8)=16
x/x-4 - 32/x的平方+16=1 x+1/x + 5X/x+1=6
(1-1/5)X=16/25 X+1/3X=120 X÷6/7=28/27÷18/15
2x²+3x-2=0 6x²+7x-3=0 3x²-14+16=0 (3x+2)²
