Question

12 x [ X - 2 ] = 3 x X + 12 

Answer 1

12 x [ X - 2] = 3 x X + 12

12 x X  - 12 x 2 = 3 x X + 12

12 x X - 24 = 3 x X + 12

12 x X - 3 x X = 12 + 24

9 x X = 36

X = 36 : 9

X = 4

Answer 2

12 x (X-2) = 3X + 12

12X - 24 = 3X +12

12X - 3X= 12 +24

(12-3) X= 36

9X        = 36

X          = 4

Answer 3

12x(X-2)=3xX+12

12X-12x2=3X+12

12X-24=3X+12

12X-3X=12+24

9X=12+24

9X=36

X=36:9

X=4

Answer 4

12 x [ X - 2] = 3 x X + 12

12 x X  - 12 x 2 = 3 x X + 12

12 x X - 24 = 3 x X + 12

12 x X - 3 x X = 12 + 24

9 x X = 36

X = 36 : 9

X = 4
