Question

Solve this system of equations using substitution. put your answer in ordered pair form, (x,y)

m+n=1000
0.05m+0.06n=57

Answer 1

solve for m in top eq m=1000-n

plug into bottom

.05*(1000-n)+.06*n=57 n=700

so plug that into top eq
m+700=1000
- 700 = 700
---------------
m=300

Answer 2

How would that be in (x,y) form?

Answer 3

if m is x and n is y then
(300,700)
