1) Solve the system, using substitution. Write the solution as an ordered pair leaving no spaces, or write no solution or infinitely many. Example: (2,1)
x = 2y - 2 and 3x - y = 14


2) Solve the system, using substitution. Write the solution as an ordered pair leaving no spaces, or write no solution or infinitely many. Example: (2,1)
2m - 3n = 6 and m = 3 - 2n


3) Solve the system, using substitution. Write the solution as an ordered pair leaving no spaces, or write no solution or infinitely many. Example: (2,1)
2m - 3n = 6 and m = 3 - 2n


4) Solve the system, using substitution. Write the solution as an ordered pair leaving no spaces or write no solution or infinitely many solutions Example: (2,1)
4x + y = 4 and y = 4 - 4x


5) Solve the system, using substitution. Write the solution as an ordered pair leaving no spaces, or write no solution or infinitely many solutions; Example: (2,1)
x = 4y and 2x + 3y = 44
