Solve for y 2.8-y/0.7=1.8

$2.8 - \frac{y}{0.7} = 1.8$

Simplify each term.

Multiply by $1$ .

$2.8 - \frac{1 y}{0.7} = 1.8$

Factor $0.7$ out of $0.7$ .

$2.8 - \frac{1 y}{0.7 (1)} = 1.8$

Separate fractions.

$2.8 - (\frac{1}{0.7} \cdot \frac{y}{1}) = 1.8$

Divide $1$ by $0.7$ .

$2.8 - (1.\overline{428571} \frac{y}{1}) = 1.8$

Divide $y$ by $1$ .

$2.8 - (1.\overline{428571} y) = 1.8$

Multiply $1.\overline{428571}$ by $- 1$ .

$2.8 - 1.\overline{428571} y = 1.8$

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

Subtract $2.8$ from both sides of the equation.

$- 1.\overline{428571} y = 1.8 - 2.8$

Subtract $2.8$ from $1.8$ .

$- 1.\overline{428571} y = - 1$

Divide each term in $- 1.\overline{428571} y = - 1$ by $- 1.\overline{428571}$ and simplify.

Divide each term in $- 1.\overline{428571} y = - 1$ by $- 1.\overline{428571}$ .

$\frac{- 1.\overline{428571} y}{- 1.\overline{428571}} = \frac{- 1}{- 1.\overline{428571}}$

Simplify the left side.

Cancel the common factor of $- 1.\overline{428571}$ .

Cancel the common factor.

$\frac{- 1.\overline{428571} y}{- 1.\overline{428571}} = \frac{- 1}{- 1.\overline{428571}}$

Divide $y$ by $1$ .

$y = \frac{- 1}{- 1.\overline{428571}}$

Simplify the right side.

Divide $- 1$ by $- 1.\overline{428571}$ .

$y = 0.7$
