Answer 1

Respuesta:

$a)4(x - 3) = 2x - 3 \\ 4x - 12 = 2x - 3 \\ 4x - 2x = - 3 + 12 \\ 2x = 9 \\ x = \frac{9}{2}$

$b) \frac{7}{4} x - 5 = 2(x - 1) \\ \frac{7}{4} x - 5 = 2x - 2 \\ 4( \frac{7}{4} x - 5) = 4(2x - 2) \\ 7x - 20 = 8x - 8 \\ - 20 + 8 = 8x - 7x \\ - 12 = x$

$c) \frac{x - 4}{2} + 3 = 4x \\ 2( \frac{x - 4}{2} + 3) = 2 \times 4x \\ x - 4 + 6 = 8x \\ x + 2 = 8x \\ 2 = 8x - x \\ 2 = 7x \\ \frac{2}{7} = x$

$d) \frac{x}{2} - 5x + 2 = - 1 \\ 2( \frac{x}{2} - 5x + 2 ) = - 1 \times 2 \\ x - 10x + 4 = - 2 \\ - 9x + 4 = - 2 \\ 4 + 2 = 9x \\ 6 = 9x \\ \frac{6}{9} = x \\ \frac{2}{3} = x$
