Question

2×+6=-12 comprobación y resultado por fis ​

Answer 1

$2x + 6 = - 12$

$2x = - 12 - 6$

$2x = - 18$

$x = \frac{ - 18}{2}$

$x = - 9$

$2( - 9) + 6 = - 12$

$- 18 + 6 = - 12$

$- 12 = - 12$

Answer 2

$\bf \textcolor{blue}{2x + 6 = - 12} \\ \\ \bf \textcolor{red}{2x = - 12 - 6} \\ \\ \bf \textcolor{blue}{2x = - 18} \\ \\ \bf \textcolor{red}{x = \frac{ - 18}{2}} \\ \\ \boxed {x = - 9} \\ \\ comprobacion \\ \\ \bf \textcolor{cyan}{2x + 6 = - 12} \\ \\ \bf \textcolor{green}{2( - 9) + 6 = - 12} \\ \\ \bf \textcolor{cyan}{ - 18 + 6 = - 12} \\ \\ \boxed{ - 12 = - 12}$
