Question

Solve this system of equations by graphing. First graph the equations, and then type the solution.3x+2y=–6x+y=–4

Answer 1

We have the following system of equations:

`\begin{gathered} 3x+2y=-6 \\ x+y=-4 \end{gathered}`

The graph of the system is the follwing:

where the red line corresponds to the first equation and the blue line to the second equation. The solution of the system is given by the intersection point of the two lines, which is the point (2, -6). Therefore, the solution is: (2, -6)
