Question

0.6(1.5x + 1.2 ) =0.8 (0.3x- 0.35 ) solve and verify plz give me correct solution of this question
​

Answer 1

Answer:

x = -1.5151..

Step-by-step explanation:

         0.6 (1.5x + 1.2) = 0.8 (0.3x - 0.35)

0.6 (1.5x)  + 0.6 (1.2) = 0.8 (0.3x) + 0.8 (-0.35)

             0.9x + 0.72 = 0.24x + (-0.28)

             0.9x + 0.72 = 0.24x - 0.28

           0.9x - 0.24x  =  - 0.28 - 0.72

                      0.66x = -1

                              x = -1/0.66

                                 = -1.515151..

Verification:

             0.6 (1.5x + 1.2) = 0.8 (0.3x - 0.35)

0.6 [1.5 ( -1.5151 ) + 1.2] = 0.8 [0.3 ( -1.5151) - 0.35]

      0.6 [-2.2727 + 1.2] = 0.8 [ -0.4545 - 0. 35 ]

              0.6 ( -1.0727) = 0.8 (0.8045)

                     - 0.6436 = -0.6436
