y=3

please mark me brainliest

Step-by-step explanation:

y(y-3)+3(y-3) = y²+5y+6

:.y²-3y+3y-3² = y²+5y+6

:. -3² = 5y+6

:. -9 = 5y+6

:. 5y = 6+9

:. 5y = 15

:. y = 15/5

:. y=3

Answer 2

Answer:

(y+3) (y-3) =y^2+ 5y +6

y(y-3) +3(y-3) =y^2+ 5y+6

y^2-3y+3y-9 = y^2+5y+6

y^2 -9=y^2+5y+6

5y=+6+9

5y=15

y=15/5

y=3
