Algebra.Com's Answer #326372 by algebrahouse.com(1659)![]() ![]() You can put this solution on YOUR website! x + 3y = 32 -------> x = -3y + 32 {subtracted 3y from both sides} \n" ); document.write( "-3x + 2y = 3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "-3x + 2y = 3 {top equation} \n" ); document.write( "-3(-3y + 32) + 2y = 3 {substituted -3y + 32, in for x, into top equation} \n" ); document.write( "9y - 96 + 2y = 3 {used distributive property} \n" ); document.write( "11y - 96 = 3 {combined like terms} \n" ); document.write( "11y = 99 {added 96 to both sides} \n" ); document.write( "y = 9 {divided both sides by 11}\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = -3y + 32 {re-arranged top equation} \n" ); document.write( "x = -3(9) + 32 {substituted 9, in for y, into new top equation} \n" ); document.write( "x = -27 + 32 {multiplied -3 by 9} \n" ); document.write( "x = 5 {added}\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = 5 and y = 9 \n" ); document.write( " For more help from me, visit: www.algebrahouse.com \n" ); document.write( " |
