$\huge{\underline{\mathscr{\purple{Hey, mate....!!!}}}}$

$\huge{\red{\mathfrak{ANSWER:-}}}$

3 (у – 7) – 2 (Зу — 4) = (2 – 5y)​

➡️ 3y - 21 - 6y + 8 = 2 - 5y
➡️ 3y - 6y - 21 + 8 = 2 - 5y
➡️ -3y - 13 = 2 - 5y
➡️ -3y + 5y = 2 + 13
➡️ 2y = 15
➡️ y = 15/2 or y = 7.5

Answer 2

Answer:

7.5

Step-by-step explanation:

3(y-7)-2(3y-4)=2-5y

3y-21-6y+8=2-5y

-3y-13=2-5y

-3y+5y=2+13

2y=15

y=7.5
