Question

Please help me for number 11.

Answer 1

B) z = w(x + y)

Explanation:

You need to isolate variable z. This means every other variable must be on the opposite side of the equal sign. Use the various properties to solve the problem.

`x=(z)/(w)-y~(Given)\\\\x+y=(z)/(w)-y+y~(Add~y~on~both~sides)\\\\x+y=(z)/(w)~(Simplify)\\\\w(x+y)=((z)/(w))w~(Multiply~w~on~both~sides)\\\\w(x+y)=z~(Simplify)`
