\n" ); document.write( "Can you help me solve the following using substitution method\r
\n" ); document.write( "\n" ); document.write( "x+2y=8\r
\n" ); document.write( "\n" ); document.write( "4x-2y=12
\n" ); document.write( "
x + 2y = 8_____x = 8 - 2y ------ eq (i)
\n" ); document.write( "4x - 2y = 12 ----- eq (ii)
\n" ); document.write( "To use substitution, just solve ONE of the 2 equations for a variable that has 1 as its coefficient, as seen above
\n" ); document.write( "4(8 - 2y) - 2y = 12 ------ Substituting 8 - 2y for x in eq (ii)
\n" ); document.write( "32 - 8y - 2y = 12
\n" ); document.write( "- 10y = 20
\n" ); document.write( "
\n" ); document.write( "Now, substitute 2 for y in eq (i) to find the value of x
\n" ); document.write( "That's ALL!! Nothing COMPLEX! \n" ); document.write( "
\n" );
