Question

14-(5×-1)(2×+3)=17-(10×+1)(×-6)

Answer 1

Respuesta:

$14 - (5x - 1)(2x + 3) = 17 - (10x +1 )(x - 6) \\ 14 - (10 {x }^{2} + 15x - 2x - 3) = 17 - (10 {x}^{2} - 60 + x- 6) \\ 14 - 10 {x}^{2} - 15x + 2x + 3 = 17 - 10 {x}^{2} + 60 - x + 6 \\ 17 - 10 {x}^{2} - 13x = 83- 10 {x}^{2} - x \\ - 13x + x = 83 - 17 \\ - 12x = 66 \\ x = 66 \div 12$
