Question

3 x ( X+2 ) = 12 x ( 6- X )+1

Answer 1

=>       3X + 6 = 72 - 12X + 1

=>        15X = 66 + 1

=>         X = 67 : 15

=>         X = 67/15

Answer 2

Ta có: 3 x ( X+2 ) = 12 x ( 6- X )+1

          3X + 6 = 72 - 12X + 1

          3X + 5 = 73 - 12X

          3X + 12X = 73 - 5

          15X = 68 

Answer 3

3 x ( X+2 ) = 12 x ( 6- X )+1

<=>3x+6=72-12x+1

<=>3x+6=73-12x

<=>3x+12x=73-6

<=>15x=67

<=>x=\(\frac{67}{15}\)
