Question

A system of equations is shown below:

n = 3m + 6
n − 2m = 2

What is the solution, in the form (m, n), to the system of equations?

(−4, −6)
(−5, −9)
(2, 6)
(1, 8)

Answer 2

Help Please

Answer 3

n - 2m = 2

3m+6 - 2m = 2 ... replace n with 3m+6 (valid because n = 3m+6 is the first equation)

3m - 2m + 6 = 2

m+6 = 2

m = ???

Answer 4

m = -4
