Question

•m =x+n/p

•d=f+rx

•-3(x+n)=r

Answer 1

Explanation:

(1) I'm not sure if the equation is
`m = (x + n)/(p)` or
`m = x + (n)/(p)`, so I'll solve both below.

`m = (x + n)/(p)`

`mp = x + n`

`x = mp - n`

`m = x + (n)/(p)`

`x = m - (n)/(p)`

(2) Answer below

`d = f + rx`

`d - f = rx`

`x = (d - f)/(r)`

(3) Answer below

`-3(x + n) = r`

`x + n = (r)/(-3)`

`x = (r)/(-3) - n`
