Algebra.Com's Answer #1910 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! You can eliminate the decimals by multiplying everything by 10.\r \n" ); document.write( "\n" ); document.write( "10(0.5x + 3.4 = 0.2x + 12.4) = 5x + 34 = 2x + 124 \n" ); document.write( "Now subtract 2x from both sides. 3x + 34 = 124 \n" ); document.write( "Subtract 34 from both sides. 3x = 90 \n" ); document.write( "Divide both sides by 3. x = 30\r \n" ); document.write( "\n" ); document.write( "Check: \n" ); document.write( "0.5(30) + 3.4 = 0.2(30) + 12.4 \n" ); document.write( "15 + 3.4 = 6 + 12.4 \n" ); document.write( "18.4 = 18.4 Solution is good.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
