Answer:

z = 15

Explanation:


(40)/(z + 1) = (15)/(6) \\

Cross multiply

That's


15(z + 1) = 40(6) \\ 15z + 15 = 240

Send 15 to the right side of the equation


15z = 240 - 15 \\ 15z = 225

Divide both sides by 15


(15z)/(15) = (225)/(15) \\

We have the final answer as

z = 15

Hope this helps you
