Solve for r 1.9r+0.1r=0.6

$1.9 r + 0.1 r = 0.6$

Step 1

Add $1.9 r$ and $0.1 r$ .

$2 r = 0.6$

Step 2

Divide each term in $2 r = 0.6$ by $2$ and simplify.

Divide each term in $2 r = 0.6$ by $2$ .

$\frac{2 r}{2} = \frac{0.6}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 r}{2} = \frac{0.6}{2}$

Divide $r$ by $1$ .

$r = \frac{0.6}{2}$

Simplify the right side.

Divide $0.6$ by $2$ .

$r = 0.3$
