You can put this solution on YOUR website!
Solve the system of equations:
\n" ); document.write( "1) \"y+=+x%2B2\"
\n" ); document.write( "2) \"2x%2By+=+11\"
\n" ); document.write( "You can use the substitution method. Substitute the \"y+=+x%2B2\" from equation 1) into equation 2) and solve for x.
\n" ); document.write( "\"2x%2B%28x%2B2%29+=+11\" Simplify.
\n" ); document.write( "\"3x%2B2+=+11\" Subtract 2 from both sides.
\n" ); document.write( "\"3x+=+9\" Divide both sides by 3.
\n" ); document.write( "\"x+=+3\" Now substitute this value of x into either of the two original equations and solve for y. Let's use equation 1)
\n" ); document.write( "\"y+=+x%2B2\" Substitute \"x+=+3\"
\n" ); document.write( "\"y+=+3%2B2\"
\n" ); document.write( "\"y+=+5\"
\n" ); document.write( "The solution is: (3, 5) and this is the point of intersection of the two lines represented by the two equations.
