Question

如题所述

Answer 1

6x=0.6+12.8×3
x=0.6÷6+12.8×3÷6
x=0.1+12.8×0.5
x=0.1+6.4
x=6.5

Answer 2

6x-12.8×3=0.6
6x=0.6+12.8×3
6X=39
x=6.5

Answer 3

6x-12.8×3=0.6
6x=0.6+12.8×3
6x=0.6+38.4
6x=39
X=6.5

Answer 4

6x-12.8×3=0.6
6x-38.4=0.6
6x=0.6+38.4
6x=39
x=39÷6
x=6.5

Answer 5

6x-38.4=0.6
6x=38.4+0.6
6x=39
