括号4.8×7.5×8等于1括号除以括号2.4×2.5×2.7括号递等式计算 括号4.8×7.5×8等于1括号除以括号2.4×2.5×2.7括号 =(4.8*7.5*8.1)÷(2.4*2.5*2.7) =(4.8÷2.4)*(7.5÷2.5)*(8.1÷2.7) =2*3*3 =18

-2.5x7.3+2.5x(-2.4)-2.5x(-1.7) 2.5(-7.3-2.4+1.7) =2.5x(-8) =-20

原式2.5x(0.8+2.4x1.25) =2.5x0.8+2.5x0.8x3x1.25 =2+2x3x1.25 =2+2.5x3 =9.5

36/46×括号23-46/36括号 =36/46x23-36/46x46/36 =18-1 =17

1399412417,你好! 解:2.4×(4.3-x)=6 4.3-x=6÷2.4 4.3-x=2.5 x=4.3-2.5 x=1.8

计算 (6-2.5)*x=3.15 x=3.15/(6-2.5) =3.15/3.5 ≈1

(2.4+24)×2.5 =(0.6×4+6×4)×2.5 =(0.6+6)×4×2.5 =6.6×10 =66

3x÷5=4.8 30÷x+25=85 13+x=28.5(要检验)2.4x=26.4(要检验)7.5—x...12.8×3=0.06 10.5+x+21=56 48-27+5x=31 题型3(带括号的方程,方法1...
