You can put this solution on YOUR website!
x = 2y-9
\n" ); document.write( "-2x+4y = 18
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - 2y = -9
\n" ); document.write( "-2x + 4y = 18
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:

\n" ); document.write( "answer:
\n" ); document.write( "This linear system is singular. It has no solution
\n" ); document.write( "---
\n" ); document.write( "you can see this by putting the equations in slope-intercept form:
\n" ); document.write( "x - 2y = -9
\n" ); document.write( "-2x + 4y = 18
\n" ); document.write( "---
\n" ); document.write( "2y = x + 9
\n" ); document.write( "4y = 2x + 18
\n" ); document.write( "---
\n" ); document.write( "y = 1/2x + 9/2
\n" ); document.write( "y = 2/4x + 18/4
\n" ); document.write( "---
\n" ); document.write( "y = 1/2x + 9/2
\n" ); document.write( "y = 1/2x + 9/2
\n" ); document.write( "---
\n" ); document.write( "the two equations are equal
\n" ); document.write( "they have an infinite number of solutions
\n" ); document.write( "they do not have a unique point of intersection
