Question

Solve simultaneous equations
you must show all your working

y=3x-2
y=x²

Answer 1

Answer:

answer is (x)^2-3x = 2

Step-by-step explanation:

y=3x-2

x^2=3x-2

x^2-3x=-2

cannot be solved any further

Answer 2

Answer:

x=2,y=4

x=1,y=1

Step-by-step explanation:

3x-2=x^2
3x-2-x^2=0 (use quadratic equation formula and find x)

x=2 or x=1

substitute in the main equations:
3x2-2=4

3x1-2=1

2^2=4

1^2=1
