Question

R + 4s = -8
3r + 2s = 6

Answer 1

R = 4

s = -3

Explanation:

r + 4s = -8

3r + 2s = 6

there are several ways to solve this system but i chose the elimination method and multiplied the second equation by -2 to get:

-6r - 4s = -12 and added it to the first equation

+ 1r + 4s = -8

-5r = -20

r = 4

plug in to find 's': 4 + 4s = -8

4s = -12

s = -3
