39=3\times 3\left(p+2\right)-2\times 2\left(p+1\right)
Multiply both sides of the equation by 6, the least common multiple of 2,3.
39=9\left(p+2\right)-4\left(p+1\right)
Multiply 3 and 3 to get 9. Multiply -2 and 2 to get -4.
39=9p+18-4\left(p+1\right)
Use the distributive property to multiply 9 by p+2.
39=9p+18-4p-4
Use the distributive property to multiply -4 by p+1.
39=5p+18-4
Combine 9p and -4p to get 5p.
39=5p+14
Subtract 4 from 18 to get 14.
5p+14=39
Swap sides so that all variable terms are on the left hand side.
5p=39-14
Subtract 14 from both sides.
5p=25
Subtract 14 from 39 to get 25.
p=\frac{25}{5}
Divide both sides by 5.
p=5
Divide 25 by 5 to get 5.
