A system of equations is shown below:
n = 3m + 7
n - 2m = 1
What is the solution, in the form (m, n), to the system of equations?
O (3,7)
(1,8)
O(-3,-2)
O(-6, -11)

Respuesta :

Answer:

Last option is the correct choice.

Step-by-step explanation:

Substitute the first equation in the second equation and then solve for the variable m.

[tex]\begin{bmatrix}3m+7-2m=1\end{bmatrix}[/tex]

[tex]m=-6[/tex]

[tex]n=3\left(-6\right)+7\\\\n=-11[/tex]

D!!!!

n=−11

m=−6

I used a graph to show you what the lines and when they would intersect would look like!!
