Question 606696: solve using the substition method. if the system has no solution or an infinite number of solutions,state this
3x + y =26
-6x + y = -37

You can put this solution on YOUR website!
-6x + y = -37
y=6x-37 substitute this to 3x + y =26
3x +6x-37 =26
9x=63
x=63/9=7
so y=6x-37=6*7-37=42-37=5
the system has only one solution
