B_ 2X+3=5/3X+4
C_X+1=8/3+2/3X
D_6+2X=18X+2

Answer 1

Respuesta:

$- 6 + 2x = 6 + 6x \\ 2x - 6x = 6 + 6 \\ - 4x = 12 \\ x = \frac{12}{ - 4} \\ \times = - 3 \\ - 2x + 3 = \frac{5x}{3} + 4 \\ - 2x + 3 = \frac{5x + 12}{3} \\ 3(- 2x + 3) = 5 \times + 12 \\ - 6x + 9 = 5x + 12 \\ - 6x + 9 = 5x + 12 \\ - 6x - 5x = 12 - 9 \\ - 11x = 3 \\ x = \frac{3}{ - 11} \\ \\ - x + 1 = \frac{8}{3} + \frac{2 \times }{3} \\ - x + 1 = \frac{24 + 6x}{9} \\ 9( - x + 1) = 24 + 6x \\ - 9x + 9 = 24 + 6x \\ - 9x - 6x = 24 - 9 \\ - 9x - 6x = 24 - 9 \\ - 15x = 15 \\ \times = \frac{15}{ - 15} \\ = - 1$
