Algebra.Com's Answer #40979 by funmath(2933)![]() ![]() ![]() You can put this solution on YOUR website! Tell wheather the given value of the varible is a solution of the equation. \n" ); document.write( " -9x+7=25+2(5-x);x=-4.\r \n" ); document.write( "\n" ); document.write( "Let x=-4 and see if both sides of the equation equal. If they do then it's a solution, if not it's not: \n" ); document.write( "-9(-4)+7=25+2(5-(-4))? \n" ); document.write( "36+7=25+2(5+4)? \n" ); document.write( "36+7=25+2(9) \n" ); document.write( "43=25+18 \n" ); document.write( "43=43!!! \n" ); document.write( "Yes it is. \n" ); document.write( "Happy Calculating!!! \n" ); document.write( " |
