solve the inequality 31< 3x+4

Sagot :

Answer:

The solution of the given inequality  x>9

Step-by-step explanation:

Explanation:-

Given that the inequality      31 < 3 x + 4

                      Subtracting '4' on both sides, we get

                                    31 - 4 < 3 x + 4 -4

                        ⇒         2 7  <  3 x

                      Dividing '3' on both sides, we get

                        ⇒         9 < x

                                   x > 9
