Solve the systems of equations by using the substitution method. (If the system is dependent, enter a general solution in terms of c.
\n" ); document.write( "{18x− 12y=24
\n" ); document.write( " −6x+ 4y= 12
\n" ); document.write( "

18x - 12y = 24 ------ eq (i)
\n" );
document.write( "- 6x + 4y = 12 ------ eq (ii)
\n" );
document.write( "- 18x + 12y = 36 ------- Multiplying eq (ii) by 3 ------ eq (iii)
\n" );
document.write( "0 = 60 ------- Adding eqs (iii) & (i)
\n" );
document.write( "From above, , so what do you think? 
\n" );
document.write( "At least 40 of these have been done for you in the past few days.
\n" );
document.write( "You still can't do these on your own?
\n" );
document.write( "I really hope that no-one will do any more for you! It's getting awfully boring and annoying doing so many of these for you! \n" );
document.write( "

\n" );
