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

Rewrite the equations;
m+4n=8
m-n=-2

Eliminating m gives;
5n=10
n=2
Replacing for n in the first equation;
m+4(2)=8
m=8
Answer;
(0, 2)
