Question

Use the substitute method to solve the system of equations.

N=-7m-4
14m+2n=-8
A. Infinite solutions
B. No solution
C. (4,8)
D. (-8,-8

Answer 1

A

Explanation:

n=-7m-4

14m+2n=-8

Substitute the first equation into the second one/

14m + 2(-7m - 4) = - 8

14m - 14m - 8 = - 8

- 8 = - 8

This means than m can be anything, and therefore there are an infinite number of possible answers.
