-35=2y+5(y+7) what is y

nydimaria [60]

$\implies \sf{ - 35 = 2y + 5(y + 7)} \\ \\$

$\implies\sf{ - 35 =2y + 5y + 35} \\ \\$

$\implies \sf- 35 - 35 = 2y + 5y \\ \\$

$\implies\sf- 70 = 7y \\ \\$

$\implies \sf y = \cancel{ \dfrac{ - 70}{7}} \\ \\$

$\implies \underline{\boxed{\bf {y = - 10}}}$

$\huge {\therefore}$ The value of y is -10.
