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
