Answer:
Well, we have to remember that we must use PEMDAS, or the order of operations, to solve the expression.
<em>Therefore, we must first either divide or multiply anything that is inside of the parentheses. (In this case divide)</em>
<em>Now solve what remains in the parentheses.</em>
<em>Finally, subtract 4 from 10 and get your answer:</em>
6
Z=kx/y
7.9=k11/14
Cross multiply
K11=7.9x14
K =7.9x14/11
K=10.1
........
Z= kx15/22
Z=10.1x15/12
Z=12.625
