Algebra.Com's Answer #112918 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Solve the equation |y-6|+2y=9 \n" ); document.write( "Rearrange: \n" ); document.write( "|y-6| = 9-2y \n" ); document.write( "y-6 = 9-2y or y-6 = -(9-2y)= 2y-9 \n" ); document.write( "3y = 15 or y = 3 \n" ); document.write( "y = 5 or y = 3 \n" ); document.write( "---------------- \n" ); document.write( "Testing: \n" ); document.write( "Does y = 5 ? \n" ); document.write( "|5-6| + 2*5 = 9 \n" ); document.write( "1+10 = 9 \n" ); document.write( "False; so y=5 is not a solution. \n" ); document.write( "------------------ \n" ); document.write( "Testing: \n" ); document.write( "Does y = 3 ? \n" ); document.write( "|3-6| + 2*3 = 9 \n" ); document.write( "3 + 6 = 9 \n" ); document.write( "True ; so y=3 is the only solution. \n" ); document.write( "------------------ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
