Algebra.Com's Answer #57596 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! what is the true equation for 2a+5b=3 is it (1/2, _4/5) or (0, 3/5). Can you show me how you came up with the answer \n" ); document.write( "----------- \n" ); document.write( "To test (1/2, -4/5) substitute 1/2 in place of a and -4/5 in place of b \n" ); document.write( "and see if you get a true statement: \n" ); document.write( "2(1/2) + 5(-4/5) = 3 \n" ); document.write( "1-4 = 3 \n" ); document.write( "-3=3 \n" ); document.write( "No, that is not true. \n" ); document.write( "---------------------- \n" ); document.write( "To test (0,3/5) substitute 0 in place of a and 3/5 in place of b. \n" ); document.write( "2*0 + 5*(3/5) = 3 \n" ); document.write( "0 + 3 = 3 \n" ); document.write( "3= 3 \n" ); document.write( "Yes, that is true. \n" ); document.write( "So (0,3/5) is the solution for the equation. \n" ); document.write( "============= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
