Questions
Use the substitution method to find the values of 
x and y in all of the simultaneous equations below. 

1) y = x2 + 2

y = 3x + 6

 

2) y = x2 – 4

y = -3x

 

3) y = x2 + 4x

y = 2x – 1

 

4) y = 2x2 + 2x + 10

y = x2 – 4x + 2

 

5) y = x2 + 2

y – x = 8

 

6) y – 5x – 1 = 0

y = 2x2 – 2

 

7) x + 7y = 14

y2 + x = 4

hint: Substitute in for y

 

8) x2 + y2 = 5

y = x + 3

 

9) y = x2 + 4x

y = 3x + 6
