Question

8x+2x-6x-13x=4elevado a 3 -4x
Me ajudem

Answer 1

$8x + 2x - 6x - 13x = 4 {}^{3} - 4x \\ 10x - 6x - 13x = 64 - 4x \\ 4x - 13x = 64 - 4x \\ - 9x = 64 - 4x \\ - 9x + 4x = 64 \\ - 5x = 64 \: . \: ( - 1) \\ 5x = - 64 \\ x = \frac{ - 64}{5}.$

Answer 2

Resposta:

x = ⁻⁶⁴/₅

Explicação passo-a-passo:

8x + 2x - 6x - 13x = 4³ - 4x

8x + 2x + 4x - 6x - 13x = 4³

14x -  19x = 64

-5x = 64

x = ⁻⁶⁴/₅
