26.4x 18x=66.6,
26.4x 18x=66.6,
26.4x 18x=66.6,
26.4x+18x=66.6
44.4x=66.6
x=66.6÷44.4
x=1.5
26.4x 18x=66.6,
(x+30)*(x-18)=x*x
26.4x+18x=66.6怎样解这个方程
26.4x+18x=66.6 解方程
26.4x+18x=66.6怎么解
26.4 x+18x=66.6解方程
26.4+x+18x=66.6解方程
（X+X)+(X-X)+(X*X)+(X/X)=100
90-x=2x(18+x)
x/(x^2+6x+18)=?
x平方+x=18,求x
26.4x+18x=66.6 0.5×6+3x=4.8 2.5x-6=18.5 x-12.56=15.7 3.6+5.4x=273.6×5-0.5x=8.5
