Question

Help please?

solve for Y
a(y+c)=b(y-c)
solve for W
A=lw+wh+lh
...?

Answer 1

I am pretty sure that the solution I attach below is the correct one :
`ay+ac=by-bc ay-by=-ac-bc y(a-b)=c(a-b)`

`y=c(a-b)/(a-b) y=c`
And what about the next part of your task, the answer is :

`A=lw+wh+lh w=(A-Ih)/(l+h)`
Do hope you will find it useful!
