规定新运算符号*的运算过程为a*b=1/3a-1/4b,解方程2*(2*x)=1*x
规定新运算符号*的运算过程为a*b=1/3a-1/4b,解方程2*(2*x)=1*x
规定新运算符号*的运算过程为a*b=1/3a-1/4b,解方程2*(2*x)=1*x
2*x=1/3×2-1/4x=2/3-1/4x
素1/3×2-1/4(2/3-1/4x)=1/3×1-1/4x
2/3-1/6+1/16x=1/3-1/4x
5/16x=-1/6
x=-8/15
2*(2*x)=1*x
2/3-1/4(2/3-x/4)=1/3-x/4
2/3-1/6+x/16=1/3-x/4
1/6=-5x/16
x=1/6÷(-5/16)
x=-8/15
