equation is:
\n" ); document.write( "1/2x-1/5=-1
\n" ); document.write( "add 1 to both sides of that equation to get:
\n" ); document.write( "(1/2)x - (1/5) + 1 = 0
\n" ); document.write( "simplify to get:
\n" ); document.write( "(1/2)x - (1/5) + (5/5) = 0
\n" ); document.write( "simplify further to get:
\n" ); document.write( "(1/2)x + (4/5) = 0
\n" ); document.write( "set the equation equal to y to get:
\n" ); document.write( "y = (1/2)x + (4/5)
\n" ); document.write( "the equation is now in y = mx + b format.
\n" ); document.write( "you can graph this equation to get:
\n" ); document.write( "\"graph%28400%2C400%2C-5%2C5%2C-5%2C5%2C%281%2F2%29x+%2B+%284%2F5%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "by substituting y for 0, you generalized the equation to be solved for all values of y, not just 0.
\n" ); document.write( "if you set y = 0 then you get your original equation back.\r
