GCSE/Simple Simultaneous Equations: (Linear)

1a) (4 marks)

6x + 2y = -3

4x – 3y = 11

1b) (4 marks)

3x – 2y = 12

X + 4y = 11

GCSE/A-Level Simultaneous Equations: (Linear)

2a) (5 marks)

X – 2y = 1

x** ^{2}** + y

**= 13**

^{2}2b) (5 marks)

X – 2y = 3

x** ^{2}** + 2y

**= 27**

^{2}2c)

L is the straight line with equation y = 2x – 1

C is the circle with equation x** ^{2}**
+ y

**= 13**

^{2}The line intersects the circle at two points

Find the coordinates of both points (5 marks)
