$y = - 3$ $color(red)(y=-3$

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

$2 y + 7 = 5 y + 16$ $2y+7=5y+16$

By transposing method:

$2 y - 5 y = 16 - 7$ $2y-5y=16-7$

$- 3 y = 9$ $-3y=9$

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

$y = - 3$ $color(red)(y=-3$

$y = - 3$ $y=-3$

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

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

$3 + 4 = 3 y + 16$ $3+4=3y+16$

Add $3$ $3$ and $4$ $4$ together

$7 = 3 y + 16$ $7=3y+16$

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

$- 9 = 3 y$ $-9=3y$

Divide both sides by $3$ $3$

$y = - 3$ $y=-3$
