− 3𝑥 + 2𝑦 = − 6 --- eq (i)
\n" );
document.write( "− 2𝑥 + 𝑦 = 6 ------ eq (ii)
\n" );
document.write( "To solve this system only ONE of the 2 equations needs to be altered. That one's eq (ii).
\n" );
document.write( "4x - 2y = - 12 ------- Multiplying eq (ii) by - 2 ------ eq (iii)
\n" );
document.write( "x = - 18 ------------- Adding eqs (iii) & (i)
\n" );
document.write( "- 2(- 18) + y = 6 ---- Substituting - 18 for x in eq (ii)
\n" );
document.write( "36 + y = 6
\n" );
document.write( "y = 6 - 36 = - 30
\n" );
document.write( " \n" );
document.write( "

\n" );
