color(red)(y=-3

#### Explanation:

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

$2 y + 7 = 5 y + 16$

By transposing method:

$2 y - 5 y = 16 - 7$

$- 3 y = 9$

$y = \frac{9}{-} 3$

color(red)(y=-3

$y = - 3$

#### Explanation:

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

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

$3 + 4 = 3 y + 16$

Add $3$ and $4$ together

$7 = 3 y + 16$

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

$- 9 = 3 y$

Divide both sides by $3$

$y = - 3$
