Algebra.Com's Answer #37012 by hulamc723(15)![]() ![]() ![]() You can put this solution on YOUR website! 2x+3y=-29 \n" ); document.write( " x+4y=-32\r \n" ); document.write( "\n" ); document.write( "solve for x by first subtracting 4y fromt he second equation to het x=-32-4y \n" ); document.write( "then plug in -32-4y into the first equation for x \n" ); document.write( "so you get 2(-32-4y)+3y=-29 or -64-8y+3y=-29 or -64-5y=-29 \n" ); document.write( "add 64 to both sides to get -5y=35 so y=-7 \n" ); document.write( "no plug y into the second equation to solve for x \n" ); document.write( "you get x+4(-7)=-32 or x-28=-32 add 28 to both sides to get x=-4 \n" ); document.write( "the answer is (-4,-7) \n" ); document.write( " \n" ); document.write( " |
