6a-2g=2
Resolver sistema lineares

Answer 1

Resposta:

$3a-g=1~~equacao~I\\ 6a-2g=2~~equacao~II\\ \\ \\ Na~equacao~I\\ \\ 3a-g=1\\ \\ -g=1-3a\\ \\ g=-1+3a\\ \\ \\ Na~equacao~II\\ \\ 6a-2g=2\\ \\ 6a-2(-1+3a)=2\\ \\ 6a+2-3a=2\\ \\ 6a-3a=2-2\\ \\ 3a=0\\ \\ a=\frac{0}{3} \\ \\ a=0\\ \\ Na~equacao~I\\ \\ 3a-g=1\\ \\ 3.0-g=1\\ \\ 0-g=1\\ \\ -g=1\\ \\ g=-1\\ \\ \\ S=\left \{ {{a=0;~g=-1} {}} \}$
