x+x÷5=36解方程

解:x+x÷5=36x+(1/5)*x=36x(1+1/5)=36(6/5)*x=36所以x=30

x/4+x/5=365x/20+4x/20=36(5x+4x)/20=369x/20=369x=36*20x=36*20÷9x=80

①X÷4+X÷5=36 ②原式=7/4*3/10+4/7*7/10 ③ 原式=5/7(53.34-2.34-1) ④原式=5/2-1/4去分母,得 =7/4(3/10+7/10) =5/7*50 =10/4-1/45X+4X=720

x =(54 +36)x5 =90x5 = 450

x÷5*3=36 解:x÷5=36÷3 x÷5=12 x=12*5 x=60

x÷5=90 x=90÷5 x=16 请采纳.

(x+2)*4=(x-2)*5 4x+8=5x-10 x=18

x÷5-36=54x÷5=54+36x÷5=90x=90*5x=450

X÷5+X÷30=3.5乘以30得 6x+x=1057x=105除以7得 x=15

x÷5-36=54 x÷5=90 x=450 满意请及时采纳
