x÷3.6=5.2解方程?x 0.7 14解方程

x÷3.6=5,解方程并验算?

x÷3.6=5

x=5x3.6

x=18

检验18÷3.6=5

x÷3.6=5 ,解方程?

解:x=3.6×5

x=18

验算:把x=18代入原式,

18÷3.6=5

望采纳!!!

解方程: (1)X÷3.6=3.5 (2)5

(1)X÷3.6=3.5,

X÷3.6×2.6=3.5×2.6,

X=9.1;

(2)5(X+4)=80,

5(X+4)÷5=80÷5,

X+4=16,

X+4-4=16-4,

X=12;

(3)6X-8=X,

6X-8-X=X-X,

5X-8=0,

5X-8+8=0+8,

5X=8;

5X÷5=8÷5;

X=1.6.

x÷3.6=2怎么解方程

x=2×3.6,

x=7.2
