Algebra.Com's Answer #178756 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Assume the problems are (x is not part of the denominator) \n" ); document.write( " \n" ); document.write( "Multiply both sides by 3 to get rid of the denominator \n" ); document.write( "2x = 3(36) \n" ); document.write( "2x = 108 \n" ); document.write( "x = \n" ); document.write( "x = 54 \n" ); document.write( ": \n" ); document.write( "Check solution by substituting 54 for x in the original equation \n" ); document.write( " \n" ); document.write( "3 cancels into 54, \n" ); document.write( "2(18) = 36 \n" ); document.write( "; \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( "Multiplying by 18 will clear the denominators here \n" ); document.write( "2(5)x = 7 \n" ); document.write( "10x = 7 \n" ); document.write( "x = \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check solution \n" ); document.write( " \n" ); document.write( "Cancel 5 into 10 \n" ); document.write( " |
