Solve for a a/5+3=12

$\frac{a}{5} + 3 = 12$

Step 1

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

Subtract $3$ from both sides of the equation.

$\frac{a}{5} = 12 - 3$

Subtract $3$ from $12$ .

$\frac{a}{5} = 9$

$\frac{a}{5} = 9$

Step 2

Multiply both sides of the equation by $5$ .

$5 \frac{a}{5} = 5 \cdot 9$

Step 3

Simplify both sides of the equation.

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

$5 \frac{a}{5} = 5 \cdot 9$

Rewrite the expression.

$a = 5 \cdot 9$

$a = 5 \cdot 9$

$a = 5 \cdot 9$

Simplify the right side.

Multiply $5$ by $9$ .

$a = 45$

$a = 45$

$a = 45$
