Solving Simultaneous Equations

Solve the following simultaneous equations:

3x + 2y = 12

5x + 3y = 19

• x = 2

  y = 3

• x = -2

  y = 3

• x = 2

  y = -3

• x = -2

  y = -3

Solve the following simultaneous equations:

7x - 4y = 20

3x + 3y = 18

• x = 4

  y = 2

• x = -4

  y = 2

• x = 4

  y = -2

• x = -4

  y = -2

Solve the following simultaneous equations:

8x - 5y = 1

3x + 4y = 18

• x = 2

  y = 3

• x = -2

  y = 3

• x = 2

  y = -3

• x = -2

  y = -3

Using the simultaneous equations 7x+7y=-42 and 4x+9y=-14, find the solution, giving your answer as a coordinate pair

• (-7, 2)

• (-8, 2)

• (-8, 3)

• (2, -8)

Using the simultaneous equations 1x+8y=12 and 4x+10y=4, find the solution, giving your answer as a coordinate pair

• (-3, 2)

• (-4, 1)

• (-4, 2)

• (2, -4)

• x = 6

  y = -2

• x = -6

  y = -2

• x = -6

  y = 2

• x = 6

  y = 2
