6y减1.2等于4.2怎么解方程？

Answer 1

6y-1.2=4.2，第一步移项，得6y=4.2+1.2；第二步合并同类项，得6y=5.4；第三步除法运算，得y=5.4/6=0.9.

Answer 2

6y - 1.2 = 4.2
6y = 4.2 + 1.2
6y = 5.4
y = 5.4/6
y = 0.9

Answer 3

6y-1.2=4.2
6y=4.2+1.2
6y=5.4
y=5.4/6
y=0.9

Answer 4

6y-1.2=4.2
6y=4.2+1.2
6y=5.4
y=0.9

Answer 5

6y-1.2=4.2
6y=4.2+1.2
6y=5.4
y=5.4÷6=0.9
