Question

Two equations are given below:

m + 3n = 10
m = n – 2

What is the solution to the set of equations in the form (m, n)? (1 point)


A. (1, 3)

B. (2, 4)

C. (0, 2)

D. (4, 6)

Answer 1

Given:
m + 3n = 10
m = n – 2

According to the 2nd equation, m=n-2. Substitute (n-2) for m in the first equation, resulting in n-2+3n=10.

Then 4n=12 and n=3. Now, using the value n=3, find m using either of the two given equations.

Answer 2

a (1,3) is the answer
