(3x-2).(7x+8)

2(x-8)+10= 3-(x - 2)

Answer 1

(3x - 2).(7x + 8)
                     = 21x^2 + 6x - 16

2(x - 8) + 10 = 3 - (x - 2)
2x - 16 + 10 = 3 - x + 2
2x + x = 3 + 2 + 16 - 10
       3x = 11
                  x = 11/3

Answer 2

(3x-2).(7x+8)

21x² + 24x - 14x - 16

21x² + 10x - 16

2(x-8)+10= 3-(x - 2)

2x - 16 + 10 = 3 - x + 2

2x - 6 = 5 - x

2x + x = 5 + 6

3x = 11

x= 11/3
