Step-by-step explanation:
Answer:
(a) The system of the equations 
has no solution.
(b) The system of the equations 
has many solutions 
Step-by-step explanation:
(a) To find the solutions of the following system of equations you must:
Multiply 
by 2:
Subtract the equations
0 = -3 is false, therefore the system of the equations has no solution.
(b) To find the solutions of the system you must:
Isolate x for 
Substitute into the second equation
The system has many solutions.
Isolate y for
