Answer:

(-4,-6).

Step-by-step explanation:

We have been given a system of equations and we are asked to find the solution for given system of equations in the form (m,n).

n=3m+6...(1)

n-2m=2...(2)

We will use substitution method to solve linear equation. Upon substituting equation (10 in equation (2) we will get,

3m+6-2m=2

Combine like terms:

m+6=2

m+6-6=2-6

m=-4

Substituting m=-4 in equation (2) we will get,

n-2\times -4=2

n+8=2

n+8-8=2-8

n=-6

Therefore, the solution for our given system of equation is (-4,-6).

n=3m+6 \\
n-2m=2 \\ \\
\hbox{substitute 3m+6 for n in the second equation:} \\
3m+6-2m=2 \\
m+6=2 \\
m=2-6 \\
m=-4 \\ \\
n=3m+6=3 \times (-4)+6=-12+6=-6 \\ \\
\boxed{(m,n)=(-4,-6)}
