2m-0.1/0.7+1/7=m/0.3
2m-0.1/0.7+1/7=m/0.3
2m-0.1/0.7+1/7=m/0.3
2m-0.1/0.7+1/7=m/0.3
2m-1/7+1/7=10m/3
2m=10m/3
m=0
因为0.1/0.7=1/7
所以-0.1/0.7+1/7=0
所以2m=m/0.3
得m=0
2m-0.1/0.7+1/7=m/0.3
m-2m-3m+4m-5m-6m+7m.2004m=?
m*m-5m-1=0则2m*m-5m+1/m*m
已知m*m+m-1=0,求m*m*m+2m*m-2005
先化简 再求值(3+m)(3-m)+m(m-6)-7,其中m=1/2
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
解方程 2m-m*m 1=2(m*m-2m)(m*m-2m)
先化简再求值(3m²+5)(-3m²+5)-m²(7m+8)(7m+8)+(2m+1)(-2m-1),其中m=-1
0.7分之2M-1+7分之1=0.3分之M M=几(0.7分之2M-1)+(7分之1)=0.3分之M M=几
已知m^2-7m+1=0,求m^2+1/m^2的值
m=?时2m-5m-1/3+7-m/2=5
若m^3+2m-1=3,则4m^3+8m-7=
m^2+m-6/m^2+2m+1÷m+3/m^+m·m^2-1/2-m 其中m=-1/2
已知m²-7m-1=0,求2m²-7m+1/m²=?
已知m^2-3m-1=0 求m^3-m^2-7m+2008的值
先化简再求值:(3+m)(3-m)+m(m-6)-7,其中m=1/2
2m-1/0.7+1/7=m/0.3一元一次方程的解法(2)
