$color(red)(y=-3$

$2y+3+4=5y+16$

$2y+7=5y+16$

By transposing method:

$2y-5y=16-7$

$-3y=9$

$y=9/-3$

$color(red)(y=-3$

$y=-3$

$2y+3+4=5y+16$

Subtract $2y$ from $2y$ and $5y$

$3+4=3y+16$

Add $3$ and $4$ together

$7=3y+16$

Subtract $16$ from $16$ and $7$

$-9=3y$

Divide both sides by $3$

$y=-3$
