Basic Math Examples

$1 A + 4 \cdot y = 240 cm$

Step 1

Multiply $A$ by $1$ .

$A + 4 y = 240 cm$

Step 2

Subtract $A$ from both sides of the equation.

$4 y = 240 cm - A$

Step 3

Divide each term in $4 y = 240 cm - A$ by $4$ and simplify.

Step 4.2.1

Factor $4$ out of $4$ .

$y = \frac{4 (60 cm)}{4 (1)} - \frac{A}{4}$

Step 4.2.2

Cancel the common factor.

$y = \frac{4 (60 cm)}{4 \cdot 1} - \frac{A}{4}$

Step 4.2.3

Rewrite the expression.

$y = \frac{60 cm}{1} - \frac{A}{4}$

Step 4.2.4

Divide $60 cm$ by $1$ .

$y = 60 cm - \frac{A}{4}$
