Question

Tìm số tự nhiên x, biết: 

12*[x-1]=10

Answer 1

\(12.\left(x-1\right)=10\)

= \(\left(x-1\right)=10:12\)

= \(\left(x-1\right)=\frac{5}{6}\)

= \(\Rightarrow x=\frac{5}{6}+1=1,8\left(3\right)\)

Answer 2

12 * ( x - 1 ) = 10

         x - 1 =  10 : 12

         x - 1 =    0

         x      = 0 + 1

         x      =    1

Answer 3

12.(x-1)=10

x-1=10:12

x-1=\(\frac{5}{6}\)

x=\(\frac{5}{6}+1\)

x=\(\frac{11}{6}\)
