Answer:

x = -5

y = -3

Step-by-step explanation:

-5^2 = 25

5 x -5 = -25

25 - 25 = 0

0 - 3 = -3

Have a nice day and mark me brainliest please! :)

Given that,

  • ⤑y = x² +5x -3 _ _ _ _ _ (i)

also,

  • ⤑y -x =2
  • ⤑y = x+2 _ _ _ _ _ _ _ _ (ii)

putting the value of y from equation (ii) in equation (i)

we get,

x +2 = x² +5x -3

x² +5x -3 - x -2 = 0

x² +5x -x -3 -2 = 0

x² +4x - 5 = 0

x² +5x - x - 5 = 0

x(x+5)-(x+5) = 0

(x-1)(x+5)= 0

hence,

★ x = 1 or -5

  • x-1 = 0 ⤏x= 1
  • x+5 = 0⤏x = -5

and

★ y = 3 or -3

  • y = x+2 ⤏ 1+2 = 3
  • y = x+2 ⤏-5+2= -3
