解方程.x+45=550 x%0.52=1.3

(1)x+45=550, x+45-45=550-45, x=505;(2)x-0.52=1.3,x-0.52+0.52=1.3+0.52, x=1.82;(3)x÷3=95, x÷3×3=95×3, x=285;(4)0.9x=2.43,0.9x÷0.9=2.43÷0.9, x=2.7.

0.52x0.45的竖式 0.52 × 0.45 = 0.234

要哪个层次的?你看看这些行不行: (0.5+x)+x=9.8÷2 2(X+X+0.5)=9.8 25000+x=6x 3200=450+5X+X X-0.8X=6 12x-8x=4.8 7.5*2X=15 1.2x=81.6 x+5.6=9.4 x-0.7x=3.6 91÷x =1.3 X+8.3=10.7 15x =3 3x-8=16 7(x-2)=2x+3 3x+9=27 18(x-2)=270 12x=3...
