S O L U T I O N :-

[tex]\implies \sf{ - 35 = 2y + 5(y + 7)} \\ \\[/tex]

[tex]\implies\sf{ - 35 =2y + 5y + 35} \\ \\ [/tex]

[tex]\implies \sf- 35 - 35 = 2y + 5y \\ \\ [/tex]

[tex] \implies\sf- 70 = 7y \\ \\ [/tex]

[tex] \implies \sf y = \cancel{ \dfrac{ - 70}{7}} \\ \\ [/tex]

[tex] \implies \underline{\boxed{\bf {y = - 10}}}[/tex]

[tex]\huge {\therefore}[/tex] The value of y is -10.
