Question

resuelva las siguientes ecuaciones con su procedimiento ​

Answer 1

Respuesta:

$a)2x + 10 = 16 \\ 2x = 16 - 10 \\ 2x = 6 \\ x = \frac{6}{2} \\ x = 3$

$b)45x = 180 + 40x \\ 45x - 40x = 180 \\ 5x = 180 \\ x = \frac{180}{5} \\ x = 36$

$c)5x + 8 = 7x - 32 \\ 8 + 32 = 7x - 5x \\ 40 = 2x \\ \frac{40}{2} = x \\ 20 = x$

$d) - 5x = - 9x - 24 \\ 24 = - 9x + 5x \\ 24 = - 4x \\ \frac{24}{ - 4} = x \\ - 6 = x$

$e)1 + 4x - 3 = 6x + 8 \\ - 2 + 4x = 6x + 8 \\ - 2 - 8 = 6x - 4x \\ - 10 = 2x \\ \frac{ - 10}{2} = x \\ - 5 = x$

$f)2x + 7 - 5x = 8 + x - 12 \\ - 3x + 7 = - 4 + x \\ 7 + 4 = x + 3x \\ 11 = 4x \\ \frac{11}{4} = x$
