Algebra.Com's Answer #434330 by Simnepi(216)![]() ![]() You can put this solution on YOUR website! to solve equations with unknown on both sides \n" ); document.write( "first eliminate the unknown from the side with least unknowns \n" ); document.write( "since -4x < 2x we eliminate the -4x by adding 4x to both sides of the equation \n" ); document.write( "giving \n" ); document.write( "2x-5+4x=7-4x+4x \n" ); document.write( "simplifying gives \n" ); document.write( "6x-5=7 \n" ); document.write( "Now we eliminate the numbers from the other side by adding 5 (to both sides) to remove the -5 \n" ); document.write( "giving \n" ); document.write( "6x-5+5=7+5 \n" ); document.write( "hence \n" ); document.write( "6x=12 \n" ); document.write( "dividing by 6 gives \n" ); document.write( "x=2 \n" ); document.write( " |
