Algebra.Com's Answer #394546 by mengayzkie(3)![]() ![]() ![]() You can put this solution on YOUR website! Given: \n" ); document.write( "Let x = the # of hazardous sites in California \n" ); document.write( " y = the # of hazardous sites in Washington\r \n" ); document.write( "\n" ); document.write( "The number of hazardous waste sites in California can be represented as: \n" ); document.write( " x = 2y - 5 which is equal to 27 \n" ); document.write( "Substitute the value of x from the given, thus giving us: \n" ); document.write( " 27 = 2y - 5\r \n" ); document.write( "\n" ); document.write( " 27 + 5 = 2y\r \n" ); document.write( "\n" ); document.write( "to solve for y:\r \n" ); document.write( "\n" ); document.write( " 32= 2y \n" ); document.write( " y = 16\r \n" ); document.write( "\n" ); document.write( "therefore there are 16 hazardous waste sites in Washington \n" ); document.write( "checking: \n" ); document.write( "substitute the values of x and y:\r \n" ); document.write( "\n" ); document.write( " 27 = 2(16) - 5 \n" ); document.write( " 27 = 32 - 5 \n" ); document.write( " 27 = 27 checked! \n" ); document.write( " \n" ); document.write( " |
