0.8x=0.12 3x+48=168 3x-x=156 3x+11=5x-5 3.8x=17.48 x÷6.7=19.43 3x+1.5x=135 100-5x=93 x+12.8=30 55-x=32.76 x÷70=4.9 5.6x=78.4 18x+21=48 8x-4x=56 3.6x+2.2x=63.8 2x+24=108(1)2x+8=16 (2)x/5=10 (3)x+7x=8 (4)9x-3x=6 (5)6x-8=4 (6)5

1)7(2x-1)-3(4x-1)=4(3x+2)-1; (2) (5y+1)+ (1-y)= (9y+1)+ (1-3y); (3) [ ( )-4 ]=x+2; 20%+(1-20%)(320-x)=320*40% 2(x-2)+2=x+1 2(x-2)-3(4x-1)=9(1-x) 11x+64-2x=100-9x 15-(8-5x)

看看这个8/(4x^2-1)+(2x+3)/(1-2x)=18/(4x^2-1)-(2x+3)/(2x-1)=18/(4x^2-1)-(2x+3)(2x+1)/ x=1/2使得分母1-2x和4x^2-1=0.舍去所以原方程解:x=-3/2(x+1)/(x+2)+(x+6)/(x+7)=(x+2

(1)x/5=10 (2)x+7x=8 (3)9x-3x=6 (4)6x-8=4 (5)5x+x=9

3X+5X=48 14X-8X=12 6*5+2X=44 20X-50=50 28+6X=88 32-22X=10 24-3X=3 10X*(5+1)=60 99X=100-X X+3=18 X-6=12 56-2X=20 4y+2=6 x+32=76 3x+6=18 16+8x=40 2x-8=8 4x-3*9=29 8x-3x=105 x-6*5=42 x+5=7 2x+3=10 12x-

异分母分数加减计算题:1/2+3/10-1/5= 1/2+3/10-1/5= 1-11/20-2/5= 2-6/7+1/7= 5/6+1/7-1/6= 5/6-(1/3+3/10)= 4/9+3/14+9/5= 8/5-5/7-2/7= 9/11-(5/7-2/11) 6/13+3/8+7/13= 9/8-(1/7+1/8)= 8/9+4/11+1/9= 2/7+5/6-1/6= 2/5+1/2-3/4= 7/8-5/12-1/3= 8/9-5/
