Respuesta :

2(x - 2) + 3(x + 1) = 9

2x - 4   + 3x + 3  = 9      distributed the 2 and 3 on the left side

               5x - 1   = 9      added like terms (2x + 3x) and (-4 + 3)

                     5x = 10      added 1 to both sides

                       x  = 2       divided 5 from both sides

Answer: x = 2
