Algebra.Com's Answer #445358 by ohtheirony(35) You can put this solution on YOUR website! You should write a system of equations to solve the problem: \n" ); document.write( "x+y=19 \n" ); document.write( "3x+4y=60 \n" ); document.write( " \n" ); document.write( "-3(x+y=19) becomes -3x-3y=-57 \n" ); document.write( " \n" ); document.write( "-3x-3y=-57 \n" ); document.write( "3x+4y=60 \n" ); document.write( "----------- \n" ); document.write( "y=3 \n" ); document.write( " \n" ); document.write( "Put y back into an equation: \n" ); document.write( "x+y=19 \n" ); document.write( "x+3=19 \n" ); document.write( "x=16 \n" ); document.write( " |
