Answer 1

Resposta:

Explicação passo-a-passo:

$\displaystyle \left[\begin{array}{ccc}x&y&1\\3&0&1\\0&-2&1\end{array}\right] =0\\\\\\\left[0.1-(-2).1\right]x-\left[3.1-0.1\right]y+3.(-2)-0.0=0\\\left[0-(-2)\right]x-\left[3-0\right]y+(-6)-0=0\\2x -3y - 6=0\\3y=2x-6\\\\y=\frac{2x}{3} -\frac{6}{3} \\\\y=\frac{2x}{3} -2$
