Algebra.Com's Answer #13974 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Solve the 2nd equation as follows: y=-3x+1 \n" ); document.write( "Substitute that into the 1st equation to get: \n" ); document.write( " 2x+2(-3x+1)=2 \n" ); document.write( "Divide thru by \"2\" to get: \n" ); document.write( " x+(-3x+1)=1 \n" ); document.write( " -2x+1 = 1 \n" ); document.write( " -2x=0 \n" ); document.write( " x=0 \n" ); document.write( "Put that value of \"x\" into either of the original equations, as follows: \n" ); document.write( "0+2y=2 \n" ); document.write( " y=1 \n" ); document.write( "Check those values for \"x\" and \"y\" in the other original equations: \n" ); document.write( "3(0)+1=1 \n" ); document.write( " 1=1 \n" ); document.write( "So the solution for the system is x=0, y=1.\r \n" ); document.write( "\n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
