1.5x+27=30+0.5x

1.5x+27=30+0.5x 1.5x+27=30+0.5x 30/x=30/(x-1.5)-x x-30-0.2x=0.5x x+0.5x=30 1.5x+27=0.5x+40还有3(x-1.8)=2(x+1.6) x+ x+(x*50%)=1.5X? (x+30)*(x-18)=x*x 解方程:x/4=30% 36/x=3/4 10/x=2.5/0.8 x/4=1.2/5 X/1.2=1.5/0.6 x/0.4=1.5/6 x/7=0.6/3.5 x/10=0.1/25-3x=8x+1 2(x-2)+2=x+1 3-x=2-5(x-1) 3x=5(32-x) 7(4-x)=9(x-4) 7x-8=2x+27 5x-18=3-2x (7x-4)+3(x-2)=2x+6 2(3x-4)+(4-x)=4x我是六年级的学生,我希望 （25-30）*1.5%x+x=1323 x=? 0.1X+0.5(27-X)=5.1 0.1x+0.5(27 x)=5. 0.5x-1.5=-1.25x x=1.5x－30 X+1.5X=30怎么算? 0.1X+0.5(30-X)=9.8 解方程x-0.5x=30 8x-0.5x=30
