Answer 1

Respuesta:

$a)2(3x - 1) = 4 \\ 6x - 2 = 4 \\ 6x = 4 + 2 \\ 6x = 6 \\ x = 1$

$c)10x - 5 + 3x - 6 = 10x + 10 \\ 13x - 11 = 10x + 10 \\ 13x - 10x = 10 + 11 \\ 2x = 21 \\ x = \frac{21}{2}$

$e) \frac{2x}{5} + \frac{3}{10} = \frac{1}{15} \\ 30( \frac{2x}{5} + \frac{3}{10} ) = 30 \times \frac{1}{15} \\ 12x + 9 = 2 \\ 12x = 9 + 2 \\ 12x = 11 \\ x = \frac{12}{11}$
