Substitute y = 1  2x into 4x + 2y = 1 to get 4x + 2(1  2x) = 1 Solve for x: 4x + 2(1  2x) = 1 4x + 2  4x = 1 0 = 1 This equation has no solution because 0 does not equal 1.

Substituting y = 1  2x into the second equation gives 4x + 2(1  2x) = 1 4x + 2  4x = 1 Solving for x gives 0 = 1, which is false. Therefore the system of equations has no solution.
