Question

0.6x0.25x =0.45x+1.2

Answer 1

We have. 0.6*0.25x = 0.45x+1.2
                  = 0.15x = 0.45x+1.2
                  = 0.15x-0.45x = 1.2
                     
                         so, -0.3x = 1.2
                       Hence, x = -4

Answer 2

0.6 × 0.25 x = 0.45x + 1.2

=> 0.15 x = 0.45 x + 1.2

=> 0.15 x - 0.45 x = 1.2

=> - 0.3x = 1.2

=> - 3x = 12

=> x = - 12/3

=> x = - 4
