Question

8m+n=34
m-3n=23
Simplify using substitution method

Answer 1

i think the first one is m+n =4.25

Answer 2

solve the second equation for m and put that in for m of the first equation. Distribute and solve and you'll get n. Then plug your n value into either equation and solve for m.

Answer 3

You can use m=3n+23

Answer 4

Sub into 8m+n=34
8(3n+23)+n=34
solve for n
