Q:
Which ordered pair (m, n) is a solution to the given system of linear equations? mc015-1.jp g (–4, –1) mc015-2.jp g (–1, –4) (11, –16)
Accepted Solution
A:
Answer:(-1,-4)Step-by-step explanation:6m-5n=14 equation 12m+2n= -10 equation 2using equation 2 we have2m=-10-2nm=-5-n equation 3using equation 1 we have6*(-5-n)-5n=14 -30-6n-5n=14-11n=14+30-11n=44n=-44/11n=-4using equation 3m=-5-nm=-5-(-4)m=-1finally we have(-1,-4)
