Answer:

a) x = 5

b) x = 4

Step-by-step explanation:

a) 4x - 3 = 2x + 7                                      collect like terms

   4x - 2x = 7 + 3                                    

   2x = 10                                                 divide both sides by the coefficient of x

   x = 5

b) 2x + 6 = 7x - 14                                     collect like terms

   2x - 7x = -14 - 6

   -5x = -20                                        divide both sidess by the coefficient of x

   x = 4
