Question

solve by the substitution method
3m+n=23
m-6n=14

Answer 1

so we solve the equation for one to substitute so we say

n=23-3m

then plug it into the other equation to solve for m

m-6(23-3m)=14

Answer 2

m-138+18m=14
19m=152
m=8

Answer 3

then we can use any of the equations to find m so you can just substitute it in and let me know what you get

Answer 4

-1

Answer 5

yes

Answer 6

and you can check it by substituting back the points
