You can put this solution on YOUR website!
We can use systems of equations!
\n" ); document.write( "We can keep the variables on the right side of the equation, while keeping the constants on the right:
\n" ); document.write( "So 3x + y - 2 = 0 becomes 3x + y = 2
\n" ); document.write( "So 2x - y - 3 = 0 becomes 2x - y = 3
\n" ); document.write( "Now we can use systems of equations:
\n" ); document.write( " 3x + y = 2
\n" ); document.write( "+ (2x - y = 3)
\n" ); document.write( "-----------------
\n" ); document.write( "3x+2x + y-y = 2+3
\n" ); document.write( "5x + 0 = 5
\n" ); document.write( "x = 1
\n" ); document.write( "Since we know what one of the variables equal, we can plug in the value of x in one (or both) of our equations.
\n" ); document.write( "3(1)+y = 2
\n" ); document.write( "y = 2-3
\n" ); document.write( "y = -1
\n" ); document.write( "Let's check if it works for our other equation as well!
\n" ); document.write( "2(1)-y = 3
\n" ); document.write( "2-y=3
\n" ); document.write( "-y = 3-2
\n" ); document.write( "-y = 1
\n" ); document.write( "y = -1
\n" ); document.write( "So, the answer to our problem is:
\n" ); document.write( "x = 1
\n" ); document.write( "y = -1
\n" ); document.write( "Also could be written as (x,y) -> (1, -1) \n" ); document.write( "
\n" );
