Question

Tìm x:

(-12)mũ 2 . x = 56 + 10 . 13 . x

Answer 1

-12^2.x=56+10.13.x

<=>144x=56+130x

<=>144x-130x=56

<=>14x=56

<=>x=4

Vậy x=4

Answer 2

(-12)².x=56+10.13.x

144x=56+130x

144x-130x=56

14x=56

X=4

Vay.......

Answer 3

   (-12) ² . x   =   56 + 10 . 13 . x

144x            = 56 + 130x

144x - 130x = 56 

 14x             = 56

 =>         x    = 56 : 14

=>          x    = 4

Answer 4

(-12)^2.x=56+10.13.x

<=>144x=56+130x

<=>144x-130x=56

<=>14x=56

=>x=\(\frac{56}{14}=4\)
