I tried to solve this system by using the graph method but, when I check it with my colleagues, the result is not correct and I do not understand why. The system is: 3x-y=7 , -12x+4y=3. The values that I decided to use for x were: 0,1,2. Thank you in advance for any help you can give me. </SPAN>\n" );
