You can put this solution on YOUR website!
FOLLOW SAME METHOD AS BELOW
\n" ); document.write( "YOU WILL GET 0=0
\n" ); document.write( "HENCE THE EQNS.ARE DEPENDENT AND CONSISTENT.
\n" ); document.write( "SO THERE ARE INFINITE SOLUTIONS..ANY VALUE FOR X AND 2X-4 OR Y IS A SOLUTION
\n" ); document.write( "EX
\n" ); document.write( "IF X=0...Y=2*0-4=-4
\n" ); document.write( "IF X=1...Y=2*1-4=-2
\n" ); document.write( "IF X=2...Y=2*2-4=0
\n" ); document.write( "ETC...
\n" ); document.write( "Can someone help me on this problem?
\n" ); document.write( "I need to solve the following system by using either addition or substitution. If a unique solution does not exist, I have to state whether the system is dependent or inconsistent.
\n" ); document.write( "10x + 2y -= 7................1
\n" ); document.write( "y = -5x + 3
\n" ); document.write( "5X+Y =3.....................2
\n" ); document.write( "MULTIPLY EQN.2 WITH 2
\n" ); document.write( "10X+2Y=6.......................3
\n" ); document.write( "SUBTRACT FROM EQN.1
\n" ); document.write( "10X+Y-10X-Y=7-6
\n" ); document.write( "0=1
\n" ); document.write( "HENCE THE EQNS. ARE INCONSISTENT .
\n" ); document.write( "THERE IS NO SOLUTION\r
