Step-by-step explanation:
-6y + 13 + 9y = 8y - 3
=> 3y - 8y = -3 - 13
=> -5y = -16
=> y = 16/5
so y= 16/5 or 3.20
Factor by grouping because there are 4 Terms

Answer:
x = 9 ⇒ second answer
Step-by-step explanation:
∵ (a + 3)(-2a² + 15a + 6) =
-2a³ + 15a² + 6a - 6a² + 45a + 18 =
-2a³ + 9a² + 51a + 18
∵ (a + 3)(-2a² + 15a + 6) = -2a³ + xa² + 51a + 18
∴ -2a³ + 9a² + 51a + 18 = -2a³ + xa² + 51a + 18
∴ x = 9
