Answer:

0 = 20 is false, therefore the system of equations has no solution.

NO SOLUTION

Explanation:

Given the system of equations


\begin{bmatrix}4x+6y=-12\\ 2x+3y=4\end{bmatrix}

solving the system by the elimination method


\begin{bmatrix}4x+6y=-12\\ 2x+3y=4\end{bmatrix}


\mathrm{Multiply\:}2x+3y=4\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:4x+6y=8


\begin{bmatrix}4x+6y=-12\\ 4x+6y=8\end{bmatrix}

subtracting the equations


4x+6y=8


-


\underline{4x+6y=-12}


0=20

0 = 20 is false, therefore the system of equations has no solution.

NO SOLUTION
