use substitution to solve each system of equations. If the system dose not have exactly one solution, state weather it has no solution or infinitely many solutions
2m+n=1
m-n=8
x=3-2y
2x+4y=6
use elimination to solve each system of equations
x+2y=6
x-3y=4
3x-y=11
x+y=5
3x+1= -7y
6x+7y=0
x - 5y=0
2x - 3y=7
2x+3y=8
x - y=2
I dont understand how to do these problems can you help me out please I just dont get it
