# Solve the following equation: z/(z + 15) = 4/9

**Solution:**

An equation is a mathematical statement with an 'equal to' symbol between two algebraic expressions that have equal values.

z / (z + 15) = 4/9

On multiplying both sides by 9(z + 15), we obtain

9z = 4(z + 15)

⇒ 9z = 4z + 60 [Using distributive property on RHS]

⇒ 9z - 4z = 60

⇒ 5z = 60

Hence,

z = 12
