Question

Y=x^2 - x - 3, y=-3X + 5. What are the solutions Of this system of equations?

Answer 1

Answer:
`(x,y)=\{(-4,17), (2,-1) \}`

Explanation:

`x^2 -x-3=-3x+5\\\\x^2 +2x-8=0\\\\(x+4)(x-2)=0\\\\x=-4, 2\\\\x=-4 \longrightarrow y=17\\\\x=2 \longrightarrow y=-1\\\\\therefore (x,y)=\{(-4,17), (2,-1) \}`
