Answer:

x = 7.5

Step-by-step explanation:

3(x+4.5)=36

Simplify the bracket : 3(x + 4.5) = 36

                                    3x + 13.5 = 36

Take 13.5 to R.H.S(right-hand side) : 3x + 13.5 = 36

                                                            3x = 36 - 13.5

                                                            3x = 22.5

Take 3 to R.H.S(right-hand side) : 3x = 22.5

                                                        x =  \frac{22.5}{3}

                                                        x = 7.5
