Solve for b -b/0.2+2.6=9.1

$- \frac{b}{0.2} + 2.6 = 9.1$

Simplify each term.

Multiply by $1$ .

$- \frac{1 b}{0.2} + 2.6 = 9.1$

Factor $0.2$ out of $0.2$ .

$- \frac{1 b}{0.2 (1)} + 2.6 = 9.1$

Separate fractions.

$- (\frac{1}{0.2} \cdot \frac{b}{1}) + 2.6 = 9.1$

Divide $1$ by $0.2$ .

$- (5 \frac{b}{1}) + 2.6 = 9.1$

Divide $b$ by $1$ .

$- (5 b) + 2.6 = 9.1$

Multiply $5$ by $- 1$ .

$- 5 b + 2.6 = 9.1$

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

Subtract $2.6$ from both sides of the equation.

$- 5 b = 9.1 - 2.6$

Subtract $2.6$ from $9.1$ .

$- 5 b = 6.5$

Divide each term in $- 5 b = 6.5$ by $- 5$ and simplify.

Divide each term in $- 5 b = 6.5$ by $- 5$ .

$\frac{- 5 b}{- 5} = \frac{6.5}{- 5}$

Simplify the left side.

Cancel the common factor of $- 5$ .

Cancel the common factor.

$\frac{- 5 b}{- 5} = \frac{6.5}{- 5}$

Divide $b$ by $1$ .

$b = \frac{6.5}{- 5}$

Simplify the right side.

Divide $6.5$ by $- 5$ .

$b = - 1.3$
