If you have an equation where the variable (x) appears more than once, you need to put the x terms on the same side and then factorise.i want help in this formula Px=x plus 3 and the question is to make x the subject of the formula .thank you in advance
So Px = x + 3 --> Px - x = 3 --> x(P-1) = 3
Can you finish it from here?

Px = x+3
Px-x=3
x(p-1)=3
x=3/(p-1)
Done.
Px-x=3
x(p-1)=3
x=3/(p-1)
Done.
