Question

I need to solve this equation: x= r-h/ y
for h and then for r

Answer 1

x= r-h/y
h= xy-r/-1
r= xy+h

Answer 2

`h=r-xy`

`r=xy+h`

Explanation:

`x=(r-h)/(y)`

Solve the equation for h

We need to get 'h' alone

`x=(r-h)/(y)`

multiply y on both sides

`xy=r-h`

Now add h on both sides

`xy+h=r`

Subtract xy from both sides

`h=r-xy`

Now solve the equation for 'r'

`x=(r-h)/(y)`

multiply y on both sides

`xy=r-h`

Now add h on both sides

`xy+h=r`

`r=xy+h`
