Question

How do you solve `-3p = 5p - 4`?

Answer 1

First, transfer `5p` to LHS as we want all variables on one side and all numbers on the other,
while transferring, if the number is in (+) it will be in (-) which is the case here,
so, the first step will be,
`-3p-5p=-4`
Subtracting `-3p` from `-5p`
`-8p=-4`
The minuses(-) cut each other,
`cancel(-)8p=cancel(-)4`
`8p=4`
4 is divided by the 8 on LHS, it will be divided because it is in multiplication here(just like the upper case scenario, it always inverses)
`p=4/8`
`p=1/2`
or,
`p=0.5`
