Answer:
According to me it should be, -2x² + 12x - 7
Step-by-step explanation:
you gotta multiply "-" between two equations by the second equation which simplifies to (x² + 5x - 6) + (-3x² + 7x - 1). Now if the two equations are simplified together:
⇒ x²- 3x² = -2x²
⇒ 5x + 7x = 12x
⇒ (-6) + (-1) = -7
Putting it all in one equation will result in: -2x² + 12x - 7
Hope this helps, good luck!
