\n" ); document.write( "I am doing the substituttion method and I can't seem to find (a,b)
\n" ); document.write( "I would like it if you showed me step by step how you find the answer.
\n" ); document.write( "The question is \r
\n" ); document.write( "\n" ); document.write( "a + 2b = 7
\n" ); document.write( "2a = 3b
\n" ); document.write( "
a + 2b = 7 ---- eq (i)
\n" ); document.write( "2a = 3b ------- eq (ii)
\n" ); document.write( "a = 7 - 2b
\n" ); document.write( "Substitute 7 - 2b for a in eq (ii) to find value of b
\n" ); document.write( "Substitute value of b into either equation to find value of a \n" ); document.write( "
\n" );
