It has been many years since I have had algebra. Please point me in the right direction with this system of linear equation...
x + 2y - 7z = -1
3x + 7y - 24z = 6
x + 4y - 12z = 26
Thank you from Montgomery, AL
Solve using the substitution method.
#1
y=5-x
3x-4y=-20
#2
x+2y=6
2x+3y=8
#3
3x+y=1
x=2y+5
#4
x+y=6
y=3-2x
#5
s+t=5
s=13-3t
#6
x-y=4
y=2-x
