24*5(24-x)*7=78
7x-24=x^2+5x
x+(x+24)+(x+4)/2=7x
2x=(5x-24)*7/16 2/5x=(x-24)*7/16
X+X/7=(X-24)+[(X-24)/5] 这个方程怎么解
问18x+37=51.4 x=?9x-7x=50 x=?5x+6x=16.94 x=?12x/4=24 x=?
30X-2X=84 5.8X-X=60 6.6X-5X=8 4X-X=24 1.5X-X=1
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
24x+9.6x=84 14.3x-7.6x=33.5 7x+8x-10x=70
9.8x-10=8x+8 150x=120(9-x) 30+5x=7x-24 4.5x x2+5x=28 5x-2.6=
(X^3+7X^2+24X+30)除(X^2+5X+13)=(2X^3+11^2+36X+45)除(2X^+7X+20)
4x+7x=150-7 19x-5(3x-4)=24 2(4x-3)+(15-2x)=24+12
(x-22)+(x-24)+(x-27)+(x-20)=x
