Question

27(5.8-x)÷3=6.3

Answer 1

解：27(5.8-X)÷3=6.3
9(5.8-X)=6.3
5.8-X=6.3÷9
5.8-X=0.7
X=5.8-0.7
X=5.1
所以原方程的解为X=5.1

Answer 2

27（5.8-x）÷3=6.3
解：27（5.8-x）÷3×3=6.3×3
27（5.8-x）=18.9
27（5.8-x）÷27=18.9÷27
5.8-x=0.7
5.8-x+x=0.7+x
0.7+x=5.8
0.7+x-0.7=5.8-0.7
x=5.1
检验：把x=5.1带入原方程，
等式左边=27（5.8-5.1）÷3=27×0.7÷3=6.3=等式右边
所以，x=5.1是原方程的解。

Answer 3

27(5.8-x)÷3=6.3
解：27(5.8-x)=6.3*3
27*5.8-27x=18.9
-27x=18.9-156.6
-27x=-137.7
x=5.1

Answer 4

原式=27*5.8-27x=6.3*3
3*5.8-3x=0.7*3
5.8-0.7=x
x=5.1

Answer 5

27（5.8-x）÷3=6.3
5.8-x=0.7
x=5.1
