Algebra.Com's Answer #48761 by rmromero(383)![]() ![]() ![]() You can put this solution on YOUR website! Here are the Steps using Substition method \n" ); document.write( "1. solve for x \n" ); document.write( "x - 2 = 3 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "3. Substitute 5 for x and solve for y. \n" ); document.write( "3x - 6y = 9 , x = 5 \n" ); document.write( "3(5) - 6y = 9 \n" ); document.write( "15 - 6y = 9 \n" ); document.write( "-6y = -6 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "4. Check the solution in both original equations. \n" ); document.write( "3x - 6y = 9 , x = 5 and y = 1 \n" ); document.write( "3(5) - 6(1) = 9 \n" ); document.write( "15 - 6 = 9 \n" ); document.write( "9 = 9 ---> True\r \n" ); document.write( "\n" ); document.write( " Therefore, the solution of the equation is (5, 1) \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " the graph of x = 5 is a vertical line along x = 5. The two line if graph together they will intersect when x = 5 and y = 1. \r \n" ); document.write( "\n" ); document.write( "============ \n" ); document.write( "Happy graphing \n" ); document.write( " |
