Show answer
x=1, y=1 (±0)
Also accept: (1,1); x=1, y=1
Common mistakes: Confusing order; giving x or y only.

Marking points
B1 · 1 mark · States x = 1 as the solution.
B2 · 1 mark · States y = 1 as the corresponding value.
Worked solution
At the intersection point, , satisfies both equations.
So, the solution is .
