Question

Make x the subject. help please

Answer 1

x =
`(N-2MP)/(2M)`

Explanation:

3M = M +
`(N)/(P+x)` ( subtract M from both sides )

2M =
`(N)/(P+x)` ( multiply both sides by P + x to clear the fraction )

2M(P + x) = N ← distribute parenthesis on left side

2MP + 2Mx = N ( subtract 2MP from both sides )

2Mx = N - 2MP ( divide both sides by 2M )

x =
`(N-2MP)/(2M)`

Answer 2

`\sf x = (n - 2mp)/(2m)`

Explanation:

`\sf 3m = m + (n)/(p + x)\\`

`\sf 3m - m = (n)/(p +x)`

`\sf 2m = (n)/(p +x)`

Now cross multiply,

2m*(p +x) = n

To open the parenthesis, multiply 2m by p and x.

2mp + 2mx = n

Isolate the term with variable 'x'

2mx = n - 2mp

Now, isolate 'x', by dividing both sides by 2m

`\sf x = (n-2mp)/(2m)`
