Algebra.Com's Answer #39044 by funmath(2933)![]() ![]() ![]() You can put this solution on YOUR website! Hi dnn, you're right, something went wrong. \n" ); document.write( "Solve system of linear equation express in ordered pair (x,y)if possible \n" ); document.write( "Add the two equations together and you eliminate the y's. Solve for x: \n" ); document.write( "x - y =4 \n" ); document.write( "2x + y =5 \n" ); document.write( "_________ \n" ); document.write( "3x+0=9 \n" ); document.write( "3x=9 \n" ); document.write( "3x/3=9/3 \n" ); document.write( "x=3 \n" ); document.write( "Substitute x=3 into one of the original equations and solve for y \n" ); document.write( "(3)-y=4 \n" ); document.write( "-3+3-y=4-3 \n" ); document.write( "-y=1 \n" ); document.write( "-(-y)=-(1) \n" ); document.write( "y=-1 \n" ); document.write( "The solution is: (x,y)=(3,-1) \n" ); document.write( "Happy Calculating, dnn!!! \n" ); document.write( " |
