Answer 1

Respuesta:

$a = 3 \\ x = \frac{3}{2} \\ x = 2$

Explicación paso a paso:

$5a - 1 = 14 \\ 5a = 14 + 4 \\ 5a = 15 \\ a = 15 \div 5 \\ a = 3$

$5x - 9 = 3(x - 2) \\ 5x - 9 = 3x - 6 \\ 5x - 3x = - 6 + 9 \\ 2x = 3 \\ x = \frac{3}{2}$

$4x - 8 = - 4(2x - 3) + 4 \\ 4x - 8 = - 8x + 12 + 4 \\ 4x + 8x - 8 = 12 + 4 \\ 4x + 8x = 12 + 4 + 8 \\ 12x = 24 \\ x = 24 \div 12 \\ x = 2$
