Use the substitution method to solve the following system of equations: 3x - 2y = 7 2x + y = 4

• x = -7/15, y = -2/7

• x = 15/7, y = 2/7

• x = 7/15, y = -2/7

• x = 15/7, y = -2/7

Use the substitution method to solve the following system of equations: x + y = 6 2x - y = 1

• x = 4/3, y = 8/3

• x = 7/3, y = 11/3

• x = 5/3, y = 7/3

• x = 2/3, y = 5/3
