Algebra.Com's Answer #1277 by indiangangsta(5)![]() ![]() ![]() You can put this solution on YOUR website! your problem is a very common one. i will show the steps below:\r \n" ); document.write( "\n" ); document.write( "2x-5y=11 \n" ); document.write( "3x+y=8\r \n" ); document.write( "\n" ); document.write( "multiply by 3 and -2 \n" ); document.write( "(3)2x-5y=11 \n" ); document.write( "(-2)3x+y=8\r \n" ); document.write( "\n" ); document.write( "Now look carefully, and u'll find ur mistake: \n" ); document.write( "6x-15y=33 --> you have to multiply the 2, the -5, and the 11 by 3, which u forgot \n" ); document.write( "-6x+-2y=-16 --> likewise, u have to multiply the 3, 1, and 8 by -2\r \n" ); document.write( "\n" ); document.write( "from there, you just continue on the regular course of action, and u'll get the right answer. \n" ); document.write( " |
