y = 4

Correct option is (C)

Step-by-step explanation:

-2x - 5y = -2 {taking minus(-) common}

⠀

2x + 5y = 2 [equation 1]

⠀

3x + 6y = -3 {taking 3 common}

⠀

x + 2y = -1 [equation 2]

⠀

{taking 2y of equation 2 on RHS}

⠀

x = -1 - 2y [equation 3]

⠀

{substituting of equation 3 in equation 1}

⠀

2(-1 - 2y) + 5y = 2

- 2 - 4y + 5y = 2

y - 2 = 2

y = 2 + 2

⠀

y = 4
