Algebra.Com's Answer #131400 by EMStelley(208)![]() ![]() You can put this solution on YOUR website! Since you did not state the question, I am going to have to assume it is to solve the system of equations. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "I will use the addition method. I will multiply the first equation by 2 and the second equation by -5. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Now, adding, we get \n" ); document.write( " \n" ); document.write( "So y=-1. To get x, you plug in y=-1 into either equation. \n" ); document.write( "5x+2(-1)=8 \n" ); document.write( "5x-2=8 \n" ); document.write( "5x=10 \n" ); document.write( "x=2 \n" ); document.write( "So the solution is (2,-1). \n" ); document.write( " |
