【解析】 将3/4乘进去消去4/3 就简便了
3/4[4/3(1/2-1/4)-8]=3/2X-5/4
(1/2-1/4)-6=2x/3-5/4
1/4-6=2x/3-5/4
2x/3=1/4+5/4-6
2x/3=-9/2
x=-3
【答案】-3
3/4[4/3(1/2-1/4)-8]=3/2X-5/4
3/4×4/3(1/2-1/4)-3/4×8=3/2X-5/4
(1/2-1/4)-6=3/2X-5/4
1/4-6=3/2X-5/4
3/2X=1/4+5/4-6
3/2X=-9/2
X=-9/2÷3/2
X=-3
3/4{3/4(1/2t-1/4)-8]=2/3t-1
1+2+3+4、、、+8+9=
(-4/3)*(-8+3/2-3/1)
2/3[3/4(3x-1/2+4)-6]-8=4
[2^4+1/4)(4^4+1/4)(6^4+1/4)(8^4+1/4)(10^4+1/4)】/[1^4+1/4)(3^4+1/4)(5^4+1/4)(7^4+1/4)(9^4+1/4)]
x×2/3+1/2=4×3/8
3/4[4/3(1/2-1/4)-8]=3/2X-5/4 简便计算!

x+3/20=46 1/2-3/4x=1/4 1/2x-3/4=1/4 1/8+3x+3/20=46 1/2-3/4x=1/4 1/2x-3/4=1/4 1/8+3/4x=1/22×4/15+x=1 3/4x=5/8x2/15 x-2/3=3/4÷1/2
3+2+5+1+8+3+6+4+125=?
已知1^4+2^4+3^4+4^4=354,求2^4+4^4+6^4+8^4=?怎么计算的?
2/3+3/4x=1 5/8x+2/3×1/2=1
计算:(-2/1)+(3/1)+(-4/1)+(9/1)+(8/1)+(-9/4)=?
(-1/2)+(1/3)+(-1/4)+(1/9)+(1/8)+(-4/9) =
(+4/3)-(+8)+(-2 3/4)-(-1 3/2)=过程=?
