Solution

$1) (2 x)^{2} + 4 (2 x) + 7 = 3 x^{2} + 8 x + 7$
Here, the square of $2 x$ is not done proper.
The correct statement will be :
$(2 x)^{2} + 4 (2 x) + 7 = 4 x^{2} + 8 x + 7$

$2) 5 y + 2 y + y - 7 y = 0$
Here, right hand side will not be zero.
The correct statement will be :
$5 y + 2 y + y - 7 y = y$
