Solve using the substitution method. If the system has no solution or an infinite number of solutions, state this.
-x + 6y = 54
3x + y = 9

1. PsyDAG

y = 9 - 3x

-x +6y = 54

Substitute 9-3x for y in second equation and solve for x. Insert that value into the first equation and solve for y. Check by inserting both values into the second equation.
