Solve for r r/10+4=5

$\frac{r}{10} + 4 = 5$

Step 1

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

Subtract $4$ from both sides of the equation.

$\frac{r}{10} = 5 - 4$

Subtract $4$ from $5$ .

$\frac{r}{10} = 1$

Step 2

Multiply both sides of the equation by $10$ .

$10 \frac{r}{10} = 10 \cdot 1$

Step 3

Simplify both sides of the equation.

Simplify the left side.

Cancel the common factor of $10$ .

Cancel the common factor.

$10 \frac{r}{10} = 10 \cdot 1$

Rewrite the expression.

$r = 10 \cdot 1$

Simplify the right side.

Multiply $10$ by $1$ .

$r = 10$
