$y = - 2$ $y=-2$

$5 + - 7 y = 19$ $5+ -7y=19$

5 increased = $5$ $5$
Product or a number, y, and -7 = $- 7 y$ $-7y$
The same as 19 = $= 19$ $=19$

Solve for $y$ $y$

$5 + - 7 y = 19$ $5+ -7y=19$ could be rewritten as $- 7 y + 5 = 19$ $-7y + 5=19$

Subtract 5 on both sides
$- 7 y + 5 - 5 = 19 - 5$ $-7y + 5 -5 =19 -5$

$- 7 y = 14$ $-7y =14$

Divide -7 on both sides
$- 7 \frac{y}{- 7} = \frac{14}{- 7}$ $-7y/-7=14/-7$

Since positive divided by negative is negative, here is the answer:
$y = - 2$ $y=-2$
