Algebra.Com's Answer #89213 by algebrapro18(249) ![]() You can put this solution on YOUR website! this is a problem involving solving a system of equations. The system is as follows: \r \n" ); document.write( "\n" ); document.write( "y = x + 10 \n" ); document.write( "x+y = 8 \r \n" ); document.write( "\n" ); document.write( "now we just plug in the first equation into the second one and solve for x. \r \n" ); document.write( "\n" ); document.write( "x + x + 10 = 8 --> combine like terms \n" ); document.write( "2x + 10 = 8 --> Subtract 10 from both sides \n" ); document.write( "2x = -2 --> divide both sides by 2 \n" ); document.write( "x = -1 \r \n" ); document.write( "\n" ); document.write( "now that we have a value for x plug that into the first equation and solve for y. \r \n" ); document.write( "\n" ); document.write( "y = -1 + 10 \n" ); document.write( "y = 9 \n" ); document.write( " |
