Step-by-step explanation:
3y²-20 = 160-2y²
3y²+2y² = 160+20
5y² = 180
y² = 180/5 = 36
y = √36 = 6

Given -
- 3y² - 20 = 160 - 2y²
⠀
To find -
- Value of y.
⠀
Solution -
- Solving the given equation for the value of y.
⠀
➛ 3y² - 20 = 160 - 2y²
⠀
➛ 3y² + 2y² = 160 + 20
⠀
➛ 5y² = 180
⠀
➛ y² = 180/5
⠀
➛ y² = 36
⠀
➛ y = √36
⠀
➛ y = 6
⠀
Hence,
- Value of y is 6.
