(5.8-1.5)*0.8=3x-1.4(5.8-1.5)*0.8=3x-1.4(5.8-1.5)*0.8=3x-1.4(5.8-1.5)*0.8=3x-1.43x=4.3x0.8=1.43x=34.
(5.8-1.5)*0.8=3x-1.4
(5.8-1.5)*0.8=3x-1.4
(5.8-1.5)*0.8=3x-1.4
(5.8-1.5)*0.8=3x-1.4
3x=4.3x0.8=1.4
3x=34.4-1.4
3x=33
x=11
(5.8-1.5)*0.8=3x-1.4
x+(x-1.4)+1.5x=33.
x+17=3(x+13),2x-11.2=0.6x,2.5x-2.17=21.9-5.8x,8(x-1.5)=x+0.6,2(0.5-x)+6=3x-2.53,用方程解
X+0.5X=3 X-0.8X=8
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
x-9/6-x+2/3=x-1 x/5-1.5=-1.2x+5 3(5-1.2x)+1.4=x-9/6-x+2/3=x-1x/5-1.5=-1.2x+53(5-1.2x)+1.4=-2(0.3x-1)1-x=-2(3x-2)-12/3x-3/2=1/4x-3/4(6x-5)+[2x-(4x-1)]=-24
3X*X-2X+6=8,X=?3X*X-2X+6=8,X=?则代数式1.5X*X-X+1=?
9x-5x=16的解 还有3x+6x=99 0.5x+1.5x=99请说清楚点 格式:5+0.8x=13.8 8x=8.8/0.8 x=11
(1)3.5x+x-14=18.4 (2)2.7*2-1.5x=0 (3)13x-6.8x+x=46.8 (4)17.5-0.5x=12.7 (5)5x-1.4x=54
5(2-x)=-(2x-7) 0.5x-2=0.8(2x-1.5) 2(x+0.5)-3(x-0.4)=5.6
一、解方程.4.5x6+4x=41 7x-3.4x=0.72 2x+1.5x=42一、解方程.4.5x6+4x=417x-3.4x=0.722x+1.5x=42(x-4.5)x6=31.8x除1.2=8(x+1.7)除3=1.4
小学四年级20道方程计算题,自己出的,不要从别的地方粘贴过来滴!34+x=78 x-12.5=47 68-x=24 0.8x=125 3x-24=4827-1.7x=13.4 1.5x-75=75 2.6+x=3.8 x÷0.8=31 x÷7=4234 x+16 x=7 7x-5x=12 8.15 +x= 45 7.6 +x-13 =1 x
1.4X*0.8=X+15 X=多少?快
3/4:x=5/16x:0.8=1/4 1.5x=4.5
2(0.7x+6)-5(0.8x+3)=8(1.5x-8)-5(3.2x-3.8) 解方程
x+ x+(x*50%)=1.5X?
3X-18=13.2 1.5X-X=6 4X+1.2X=26
x+1.5x=7500 x-0.85x=3 4x-1.2=74
