Solving Simultaneous Linear Equations

Which are the correct ways to solve the equations using elimination method? (you may choose more than one answer) 12x − 8y = −8 --- (1) 4x + 8y = 40 --- (2)

• (1) + (2)

• (1) - (2)

• 3 X (2) − (1)

• 3 X (2) + (1)

Solve and find the value of k for the following simultaneous equations:

3h − k = 2

2h + k = 8

• 2

• 4

• 7

• 10

Solve these simultaneous equations.

• x = 6 , y = 20

• x = 6 , y = 27

• x = 0 , y = 3

• x = -1 , y = -3

Solve these simultaneous equations

• x = 0 & y = 5

• x = -3 & y = 6

• x = 2 & y = 5

• x = -3 & y = 5

Solve for (x,y)

-2x + 6y = 16

-4x - 3y = 2

• (2,2)

• (-2, -2)

• (-2,2)

• (2,1)

Solve:

3x - 4y = 26

2x - 4y = 20

• x = 6

  y = -2

• x = -6

  y = -2

• x = -6

  y = 2

• x = 6

  y = 2

Solve:

4x - y = 17

7x - y = 32

• x = 5

  y = 3

• x = -5

  y = 3

• x = 5

  y = -3

• x = -5

  y = -3

Solve:

3x + 2y = 15

7x + 2y = 19

• x = 1

  y = 6

• x = -1

  y = 6

• x = 1

  y = -6

• x = -1

  y = -6

Solve:

2x + 5y = 29

x + 5y = 22

• x = 7

  y = 3

• x = -7

  y = -3

• x = 7

  y = -3

• x = -7

  y = 3

Solve these simultaneous equations

• x = 3 and y = 10

• x = 10 and y = 3

• x = 4 and y = 9

• x = 9 and y = 4
