Solve for m 0.5-0.2+2m=-0.3+3.5m

$0.5 - 0.2 + 2 m = - 0.3 + 3.5 m$

Subtract $0.2$ from $0.5$ .

$0.3 + 2 m = - 0.3 + 3.5 m$

Move all terms containing $m$ to the left side of the equation.

Subtract $3.5 m$ from both sides of the equation.

$0.3 + 2 m - 3.5 m = - 0.3$

Subtract $3.5 m$ from $2 m$ .

$0.3 - 1.5 m = - 0.3$

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

Subtract $0.3$ from both sides of the equation.

$- 1.5 m = - 0.3 - 0.3$

Subtract $0.3$ from $- 0.3$ .

$- 1.5 m = - 0.6$

Divide each term in $- 1.5 m = - 0.6$ by $- 1.5$ and simplify.

Divide each term in $- 1.5 m = - 0.6$ by $- 1.5$ .

$\frac{- 1.5 m}{- 1.5} = \frac{- 0.6}{- 1.5}$

Simplify the left side.

Cancel the common factor of $- 1.5$ .

Cancel the common factor.

$\frac{- 1.5 m}{- 1.5} = \frac{- 0.6}{- 1.5}$

Divide $m$ by $1$ .

$m = \frac{- 0.6}{- 1.5}$

Simplify the right side.

Divide $- 0.6$ by $- 1.5$ .

$m = 0.4$
