document.write( "This is my problem 3x+4y=12 (0, ) ( ,3/4) ( ,0) (8/3, ) I have spent about 4 hours working on this. I tried solving for both x and y then plugging the number in. That didnt work out. I have tried graphing it to see if I could make more sense out of it that way, and that didnt help me much, and I believe it confused me worse. PLease Help!! \n" );

Algebra.Com's Answer #49442 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! This is my problem 3x+4y=12 (0, ) ( ,3/4) ( ,0) (8/3, ) \n" ); document.write( "If x=0, you get 0+4y=12; y=3. So the point is (0,3) \n" ); document.write( "If x=8/3, you get 3(8/3)+4y=12; 8+4y=12; 4y=4; y=1. So the point is (8/3,1) \n" ); document.write( "If y=3/4, you get 3x+4(3/4)=12; 3x+3=12; 3x=9; x=3. So the point is (3,3/4) \n" ); document.write( "If y=0, you get 3x+0 = 12; x=4. So the point is (4,0) \n" ); document.write( "------------ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
