Solve the following simultaneous equations using substitution method
\(x + 15y = 20\)
\(3x - 8y = 7\)
\(x = 5,\,\,\,y = 1\)
\(9x -2y = 20\)
\(5x +y = 9\)
\(x = 2,\,\,\,y = - 1\)
\(6x - y = 15\)
\(11x + 7y = 1\)
\(x = 2,\,\,\,y = - 3\)
\(3x + 17 = 11y\)
\(3y = x + 1\)
\(x = 20,\,\,\,y = 7\)
\(5x - 4y = 8\)
\(2x + y = 50{\rm{ }}\)
\(x = 16,\,\,\,y = 18\)
