解方程6.5x-2(5-x)=27.4
解方程6.5x-2(5-x)=27.4

解方程6.5x-2(5-x)=27.4
6.5x-2(5-x)=27.4
6.5x-2×5+2x=27.4
6.5x+2x=27.4+10
8.5x=37.4
x=37.4÷8.5
x=4.4

6.5x-2(5-x)=27.4
6.5x -10 + 2x = 27.4
8.5x = 37.4
x = 4.4

6.5x-2(5-x)=27.4
6.5x-10+2x=27.4
6.5x+2x=27.4+10
8.5x=37.4
x=37.4/8.5
x=4.4

6.5x-2(5-x)=27.4
8.5x =37.4
x=4.4

6.5X-10+2X=27.4
6.5X+2X=27.4+10
7.5X=37.4
X=自己解

6.5x-2(5-x)=27.4
6.5x-2×5+2x=27.4
6.5x+2x=27.4+10
8.5x=37.4
x=37.4÷8.5
x=4.4

解
6.5x-10+2x=27.4
8.5x=37.4
x=4.4

6.5x-10+2x=27.4
8.5x=37.4
