Algebra.Com's Answer #299760 by mananth(16946)![]() ![]() You can put this solution on YOUR website! 2/3x + y = 13 , -x + 2y + 5\r \n" ); document.write( "\n" ); document.write( "Whenever you get a fraction in an equation convert the fraction into a whole number by multiplying by the denominator or multiply by the LCD iof both are fractions. \n" ); document.write( "2x/3+y = 13 \n" ); document.write( "multiply by 3 \n" ); document.write( "2x+3y= 39 ...............1 \n" ); document.write( "-x+2y= 5.................2 ( hope this is correct equation)\r \n" ); document.write( "\n" ); document.write( "Eliminate y \n" ); document.write( "multiply (1)by -2 \n" ); document.write( "Multiply (2) by 3 \n" ); document.write( "-4x-6y=-78 \n" ); document.write( "-3x+6y= 15 \n" ); document.write( "Add the two equations \n" ); document.write( "-7x=-63 \n" ); document.write( "/-7 \n" ); document.write( "x=9 \n" ); document.write( "plug value of x in (1) \n" ); document.write( "2x+3y=39 \n" ); document.write( "18+3y=39 \n" ); document.write( "3y=39-18 \n" ); document.write( "3y=21 \n" ); document.write( "y=7 \n" ); document.write( " \n" ); document.write( " |
