solve the following proportion
7/2 = (z-5)/(z-3)
To solve a proportion, just cross-multiply.
7(z - 3) = 2(z - 5) {cross-multiplied diagonally}
7z - 21 = 2z - 10 {used distributive property}
7z = 2z + 11 {added 21 to both sides}
5z = 11 {subtracted 2z from both sides}
z = 11/5 {divided both sides by 5}
