ELIMINATION METHOD
\n" ); document.write( "3X-5Y=66 MULTIPLY BY 3
\n" ); document.write( "3Y=8-5X
\n" ); document.write( "5X+3Y=8 MULTIPLY BY 5 & ADD.
\n" ); document.write( "9X-15Y=198
\n" ); document.write( "25X+15Y=40
\n" ); document.write( "------------------
\n" ); document.write( "34X=238
\n" ); document.write( "X=238/34
\n" ); document.write( "X=7 ANS.
\n" ); document.write( "3*7-5Y=66
\n" ); document.write( "21-5Y=66
\n" ); document.write( "-5Y=66-21
\n" ); document.write( "-5Y=45
\n" ); document.write( "Y=45/-5
\n" ); document.write( "Y=-9 ANS.
\n" ); document.write( "PROOF:
\n" ); document.write( "5*7+3*-9=8
\n" ); document.write( "35-27=8
\n" ); document.write( "8=8
\n" ); document.write( "SUBSITUTION METHOD
\n" ); document.write( "15X-10Y=-5
\n" ); document.write( "5Y+3+10X [no = sign in this equation. can't solve.
\n" ); document.write( "
