Answer 2

Question.

solve➝ $\sf\green{z/(z+15) = 4/9}$

Solution.

☞$\sf\red{Appling\:cross\: multiplication}$

➝$\sf\green{9(z) = 4 ( z+15)}$

➝$\sf\green{ 9z = 4z + 60}$

➝$\sf\green{9z - 4z = 60}$

➝$\sf\green{ 5z = 60}$

➝$\sf\green{ z = 60/5}$

➝$\sf\red{z = 12}$

So, the value of z is $\sf\green{12}$
