24x+180-32x=10224x+180-32x=10224x+180-32x=10224x+180-32x=102180-102=32x-24x8x=78x=39/424x+180-32x=10
24x+180-32x=102
24x+180-32x=102
24x+180-32x=102
24x+180-32x=102
180-102=32x-24x
8x=78
x=39/4
24x+180-32x=102
-8x=-78
x=39/4
24x+180-32x=102
(24-32)x=102-180
-8x=-78
x=78/8
x=9.75 或39/4
式子左边24x-32x合并为-8x,把180移到右边,即-8x=102-180,x=9.75
24x+180-32x=102
180=( )x( )x( )x( ) ×( )
(16x-13)/(4x-3)-(20x-24)/(4x-5)=(32x-30)/(8x-7)-(40x-43)/(8x-9)求x
matlab中a=[x(11)/x,x(12)/x;x(21)/x,x(22)/x;x(31)/x,x(32)/x;x(41)/x,x(42)/x;x(51)/x,x(52)/x]咋错了
12x+24-6x=102
(32-2x)x=24
(x-5)(x-4)=102x²+x+3=03x²-32x-48=03x²+6x=1
解方程(12x-10)/(4x-3)+(32x-34)/(8x-9)=(24x-23)/(8x-7)+(16x-19)/(4x-5)
12x-10/4x-3 + 32x-34/8x-9 = 24x-23/8x-7 + 16x-19/4x-5
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)....
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)
(X+X)+(X-X)+(X*X)+(X/X)=100
180=( )x( )=( )X( )=( )X( )
x-2=(104-x)+2 6x-59=10x-75 (x+10)+(x-15)=280-x4(x-62)=x-38 60x-40=(60+20)*(x-5) 32x+32*0.5-25x+64x=24x+496-49x x+15=3*(109-x ) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7) 13x-4(2x+5)=17(x-2)-4(2x-1) (13x+8)/3=5x-1x-60=2[(3561-x)+100]+1 (x+9)+12=2[(x-9)-1
X÷48%=X+(X+32)
x平方=(24-x)(12-x)
X(X+1)(X+2)=24
20%x+80%(x-180)=32%(x+x-180)怎么算
