Question

Resolver: 5x -30 = -45 4x -9 = 2x +18 2/3=3x-6/-x+3

Answer 1

Explicación paso a paso:

$5x - 30 = - 45 \\ 5x = - 45 + 30 \\ 5x = - 15 \\ x = \frac{ - 15}{5} \\ x = - 3$

$4x - 9 = 2x + 18 \\ 4x - 2x = 18 + 9 \\ 2x = 27 \\ x = \frac{27}{2}$

$\frac{2}{3} = \frac{3x - 6}{ - x + 3} \\ \\ 2( - x + 3) = 3(3x - 6) \\ - 2x + 6 = 9x - 18 \\ 18 + 6 = 9x + 2x \\ 24 = 11x \\ \frac{24}{11} = x$
