• solve the system of equations by substitution. what is the solution for x? 2x + y = 1 4x + 2y = −1

  • Answers

  • 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.
