Solve the system by graphing, addition and substitution methods.
\n" ); document.write( "4x – 4y = –8 .....1
\n" ); document.write( "y = 2 + x ................2
\n" ); document.write( "PUTTING 2 IN EQN.1
\n" ); document.write( "4X-4(2+X)=-8
\n" ); document.write( "4X-8-4X=-8
\n" ); document.write( "0=0
\n" ); document.write( "HENCE THE EQNS. ARE DEPENDENT/ CONSISTENT.SO THERE WILL BE INFINITE SOLUTIONS..SAY
\n" ); document.write( "X=0... Y=2...OR
\n" ); document.write( "X=1..Y=3..OR
\n" ); document.write( "X=2..Y=4..ETC..IN FACT
\n" ); document.write( "X,X+2.WITH ANY VALUE FOR X IS A SOLUTION SET.
\n" ); document.write( "X....................0.................1......................2...ETC
\n" ); document.write( "Y=2+X................2..................3......................4...ETC
\n" ); document.write( "Y=(4X+8)/4...........2..................3.....................4....ETC
\n" ); document.write( "\"+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+x%2B2%2C%284%2Ax%2B8%29%2F4%29+\"
\n" ); document.write( "THE 2 GRAPHS ARE IDENTICAL OR COINCIDENT.SO INFINITE SOLUTIONS ,WITH ANY POINT ON THE GRAPH BEING A SOLUTION.\r
