Question

-x - 3y = 6, 2x + 3 = -8 equivalent equation and solution

Answer 1

x = -11/2 , y = -1/6

Explanation:

Given:

`\begin{bmatrix}-x-3y=6\\ 2x+3=-8\end{bmatrix}`

Solve:

`\mathrm{Substitute\:}x=-(11)/(2)`

`\begin{bmatrix}-\left(-(11)/(2)\right)-3y=6\end{bmatrix}`

`Simplify`

`\begin{bmatrix}(11)/(2)-3y=6\end{bmatrix}`

`\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}`

`x=-(11)/(2),\:y=-(1)/(6)`

Hence, x = -11/2 , y = 1/6
