7-p=3p%2B5 Start with the given equation.


-p=3p%2B5-7 Subtract 7 from both sides.


-p-3p=5-7 Subtract 3p from both sides.


-4p=5-7 Combine like terms on the left side.


-4p=-2 Combine like terms on the right side.


p=%28-2%29%2F%28-4%29 Divide both sides by -4 to isolate p.


p=1%2F2 Reduce.

7+-+p+=+3p+%2B+5
Subtract 5 from both sides of the equation
7-5-p=3p%2B5-5
2-p=3p add p to both sides of the equation
2=3p%2Bp
2=4p
4p=2 divide by 4
p=1%2F2
