You can put this solution on YOUR website!
Here are the equations:
\n" ); document.write( "(i) 10x + 3y = 8
\n" ); document.write( "(ii) 2x + y = 2
\n" ); document.write( "Solve (ii) for y. It is easiest.
\n" ); document.write( "(i) 10x + 3y = 8
\n" ); document.write( "(iii) y = -2x + 2
\n" ); document.write( "substitute (iii) into (i) to get
\n" ); document.write( "10x + 3(-2x+2) = 8
\n" ); document.write( "10x - 6x + 6 = 8
\n" ); document.write( "4X = 2
\n" ); document.write( "X = 1/2
\n" ); document.write( "find Y.
\n" ); document.write( "Y = 1.
\n" ); document.write( "(1/2, 1)
\n" ); document.write( "
\n" );
