Algebra.Com's Answer #40267 by funmath(2933)![]() ![]() ![]() You can put this solution on YOUR website! Without parenthesese we don't know where your fractions begin and end. If I am misinterpretting this let me know: \n" ); document.write( "L1) \n" ); document.write( "L2) \n" ); document.write( "Multiply L1 by 3 and L2 by 7 to clear the fractions. \n" ); document.write( "L1) \n" ); document.write( "L2) \n" ); document.write( "Now multiply L1 by 4 and L2 by -3, add L1+L2 to eliminate the x's and solve for y: \n" ); document.write( "L1) \n" ); document.write( "L2) \n" ); document.write( ": \n" ); document.write( "12x-20y=84 \n" ); document.write( "-12x-21y=39 \n" ); document.write( "____________ \n" ); document.write( "-41y=123 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Substitute -41/14 in for y in one of the equations and solve for x. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "(x,y)=(2,-3) \n" ); document.write( "Happy Calculating!!!\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
