Equation 1: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=a0ddd35abb1d2de1577a6326ce45ef4f.png\")
Equation 2: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=347710bac895bee85f3d0f14b6a1c70e.png\")
.
Observe the coefficient of each term, the coefficient of y - term is one in the first and second equation, so the best method is substitution method to solve the system of equations.
\The second equation, ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=347710bac895bee85f3d0f14b6a1c70e.png\")
is already solved for y.

The value of substitute in the first equation, ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=d7bb6937a1221052de9f645b45b46811.png\")
to find x.

This is false statement, so there is no solution.
