ayudeme porfavor siiino entiendo ​

Answer 1

Explicación paso a paso:

EJERCICIO A

$6x + 3 = 9x + 6 \\ 6x + 3 - 6x = 9x + 6 - 6x \\ 0 + 3 = 3x + 6 \\ 3 - 6 = 3x + 6 - 6 \\ - 3 = 3x \\ \frac{ - 3}{3} = \frac{3x}{3} \\ - 1 = x$

EJERCICIO B

$4x + x + 2 = 10x - 13 \\ 5x + 2 = 10x - 13 \\ 5x - 5x + 2 + 13 = 10 - 5x - 13 + 13 \\ 15 = 5x \\ \frac{15}{5} = \frac{5x}{5} \\ 3 = x$

EJERCICIO C

$8y + 2y = 20y + 10 \\ 10y = 20y + 10 \\ 10y - 10y - 10 = 20y - 10y + 10 - 10 \\ 0 - 10 = 10y + 0 \\ - 10 = 10y \\ \frac{ - 10}{10} = \frac{10y}{10} \\ - 1 = y$
