How to use SADMEP? `285+h/25 = 300`

Answer 1

`h = 375`

Explanation:

You might recognise that SAMDEP is just PEDMAS in reverse.

PEDMAS is used for simplifying an expression which has different operations - work from strongest to weakness operations.

In solving an equation or changing the subject of a formula you do exactly the opposite.
Get rid of any other terms by adding or subtracting,
then get rid of coefficients by multiplying or dividing
then isolate the variable and get rid of powers or parentheses

`285+h/25=300" "larr` subtract `285` from both sides "S"

`285 color(red)(-285)+h/25=300color(red)(-285)`

`h/25 color(blue)(xx25)= 15color(blue)(xx25)" "larr` Multiply by `25" "` "M"

`h= 375`
