Answer:

33.5

Explanation:

The given expression is;

          2134211  - 12431  - 24143x  = 1312431

To solve this problem, simplify the similar terms;

          2121780 - 24143x  = 1312431

                  - 24143x  = 1312431 - 2121780

                   - 24143x  = -809349

     divide both sides of the expression by -24143;

                      x  = 33.5
