Sejam dadas as matrizes $\displaystyle{A}={\left[\matrix{{1}&{4}\\{3}&{5}\\{0}&{2}\\-{1}&{7}}\right]}$ , $\displaystyle{B}={\left[\matrix{{1}&{2}\\{1}&{2}\\{1}&{3}\\{1}&{3}}\right]}$ e $\displaystyle{C}={\left[\matrix{{4}&{1}\\{5}&{1}\\{7}&{2}\\{11}&{3}}\right]}$ resolva a equação matricial

$\displaystyle{X}+{C}={2}{A}+{3}{B}$ , determinando a matriz $\displaystyle{X}$ e, em seguida, assinale a alternativa CORRETA, que representa a matriz procurada.

$\displaystyle{X}={\left[\matrix{{1}&{13}\\{2}&{5}\\{14}&{10}\\-{10}&{20}}\right]}$
$\displaystyle{X}={\left[\matrix{-{4}&{11}\\{1}&{13}\\-{4}&{15}\\-{1}&{2}}\right]}$
$\displaystyle{X}={\left[\matrix{{1}&{1}\\{3}&{15}\\-{2}&{12}\\-{11}&{21}}\right]}$
$\displaystyle{X}={\left[\matrix{{1}&{13}\\{4}&{15}\\-{4}&{11}\\-{10}&{20}}\right]}$
$\displaystyle{X}={\left[\matrix{{10}&{15}\\-{4}&{20}\\-{1}&{13}\\-{11}&{2}}\right]}$
