Please help me out.thank you

Answer 1

`y(he+b)=d+z`

solve for y by dividing both sides by (he+b)

`\begin{gathered} y(\mleft(he+b\mright))/(\mleft(he+b\mright))=(d+z)/(\mleft(he+b\mright)) \\ y=(d+z)/((he+b)) \end{gathered}`

to solve for e start by dividing by y on both sides

`\begin{gathered} (y(he+b))/(y)=(d+z)/(y) \\ he+b=(d+z)/(y) \end{gathered}`

continue by substracting b on both sides

`\begin{gathered} he+b-b=(d+z)/(y)-b \\ he=(d+z)/(y)-b \end{gathered}`

divide by h on both sides to solve for e

`\begin{gathered} (he)/(h)=(1)/(h)\cdot((d+z)/(y)-b) \\ e=(d+z)/(hy)-(b)/(h) \end{gathered}`

ANSWER

`y=(d+z)/((he+b))`

`e=(d+z)/(hy)-(b)/(h)`
