Question

Two equations are given below:

m + 4n = 8
m = n − 2

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

A) (4,6)
B) (2,4)
C) (0,2)
D) (6,8)

Answer 1

2nd equation is in y form
so you can substitute that into 1st equation :-)

Answer 2

replace m by n-2 and then combine like terms
