  2. Using the hints present click and drag the correct part of the solution to it’s correct place in the answer. correct QUESTION …..eqn 1 2x + 2y = 6 3x = 15 …..eqn 2 = 5 + 4 = 9 …..eqn 1 + eqn 2 = = …..solved for x x – 2y = 9 = …..sub x = 5 in eqn 1 and solve x = 5 = = = 10 + 2y = 6 …..solved for y 5 – 2(-2) = 9 x = 5 and y = -2 solution 2y = -4 = check in eqn 2 2 x 5 + 2y = 6 = y = -2

  3. Using the hints present click and drag the correct part of the solution to it’s correct place in the answer. correct ANSWER …..eqn 1 2x + 2y = 6 …..eqn 2 = x – 2y = 9 …..eqn 1 + eqn 2 3x = 15 = = x = 5 …..solved for x 2 x 5 + 2y = 6 = …..sub x = 5 in eqn 1 and solve 10 + 2y = 6 = = 2y = -4 = y = -2 …..solved for y x = 5 and y = -2 solution 5 – 2(-2) = 9 = check in eqn 2 = 5 + 4 = 9

  4. Using the hints present click and drag the correct part of the solution to it’s correct place in the answer. correct QUESTION …..eqn 1 6x + 3y = 21 …..eqn 2 2 x 2.5 + 3y = 11 = 3y = 6 …..eqn 1 - eqn 2 = = …..solved for x 4x = 10 = …..sub x = 2.5 in eqn 2and solve = 6 x 2.5 + 3 x 2 = 21 = = …..solved for y 2x + 3y = 11 x = 2.5 and y = 2 solution 5 + 3y = 11 = check in eqn 1 15 + 6 = 21 = x = 2.5 y = 2

  5. Using the hints present click and drag the correct part of the solution to it’s correct place in the answer. correct ANSWER …..eqn 1 6x + 3y = 21 …..eqn 2 2x + 3y = 11 = …..eqn 1 - eqn 2 4x = 10 = = x = 2.5 …..solved for x = …..sub x = 2.5 in eqn 2and solve 2 x 2.5 + 3y = 11 5 + 3y = 11 = = 3y = 6 = y = 2 …..solved for y x = 2.5 and y = 2 solution = 6 x 2.5 + 3 x 2 = 21 check in eqn 1 15 + 6 = 21 =

  6. Using the hints present click and drag the correct part of the solution to it’s correct place in the answer. correct QUESTION …..eqn 1 3x + 4y = 41 …..eqn 2 4y = 20 = …..eqn 3 = eqn 1 x5 = …..eqn 4=eqn 2x4 28 - 25 = 3 = …..eqn 3 +eqn 4 = = 16x – 20y = 12 …..solved for x y = 5 = …..sub x = 7 in eqn 1and solve = 31x = 217 = = 3 x 7 + 4y = 41 …..solved for y x = 7 and y = 5 solution 4 x 7 - 5 x 5 = 3 21 + 4y = 41 = check in eqn 2 x = 7 = 4x - 5y = 3 15x + 20y = 205

  7. Using the hints present click and drag the correct part of the solution to it’s correct place in the answer. correct ANSWER …..eqn 1 3x + 4y = 41 …..eqn 2 4x - 5y = 3 = …..eqn 3 = eqn 1 x5 15x + 20y = 205 = …..eqn 4=eqn 2x4 16x – 20y = 12 = …..eqn 3 +eqn 4 31x = 217 = x = 7 = …..solved for x = 3 x 7 + 4y = 41 …..sub x = 7 in eqn 1and solve = 21 + 4y = 41 = 4y = 20 = y = 5 …..solved for y x = 7 and y = 5 solution = 4 x 7 - 5 x 5 = 3 check in eqn 2 28 - 25 = 3 =
