P=3
Step-by-step explanation:
To solve for p, we can simply substitute his answer in place of x, changing the equation to 4(-5+p)=12. Now we just have to solve it.
1. Apply the distributive property. We can do this by multiplying 4 by -5 and p. Our equation is now -20+4p=12
2. Add 20 on both sides. Since the 20 is negative, we would add it on both sides, canceling out the -20 and leaving us with the equation 4p=32.
3. Now divide 12 by 4. We want to get p alone by itself, so we divide both sides by 4, leaving us with the solution p=3.
Hope this helps! :D
