Solve for y -7.75=-y/0.8-3.5

$- 7.75 = - \frac{y}{0.8} - 3.5$

Rewrite the equation as $- \frac{y}{0.8} - 3.5 = - 7.75$ .

$- \frac{y}{0.8} - 3.5 = - 7.75$

Simplify each term.

Multiply by $1$ .

$- \frac{1 y}{0.8} - 3.5 = - 7.75$

Factor $0.8$ out of $0.8$ .

$- \frac{1 y}{0.8 (1)} - 3.5 = - 7.75$

Separate fractions.

$- (\frac{1}{0.8} \cdot \frac{y}{1}) - 3.5 = - 7.75$

Divide $1$ by $0.8$ .

$- (1.25 \frac{y}{1}) - 3.5 = - 7.75$

Divide $y$ by $1$ .

$- (1.25 y) - 3.5 = - 7.75$

Multiply $1.25$ by $- 1$ .

$- 1.25 y - 3.5 = - 7.75$

Move all terms not containing $y$ to the right side of the equation.

Add $3.5$ to both sides of the equation.

$- 1.25 y = - 7.75 + 3.5$

Add $- 7.75$ and $3.5$ .

$- 1.25 y = - 4.25$

Divide each term in $- 1.25 y = - 4.25$ by $- 1.25$ and simplify.
