Subtract 3 from both sides
simplify 12 - 3 to 9
break down the problem into these two equations
1 + p = 9 and -(1 + p) = 9
solve the first equation 1 + p = 9 and that would be 8 since 1 + 8 = 9 is true.
solve the second equation -(1 + p) = 9 and just simplify brackets and add 1 to both sides then add 9 + 1 and lastly multiply both sides by -1 and p = -10.
Gather both solutions
Answers: p = -10, 8

Answer:
1
Step-by-step explanation: 1x3=3+4=7
Answer:
Multiplication...
Multiplication is just like adding a number to itself multiple times
For example: 3x3 is the same as 3+3+3
Division...
Division is basically splitting up a number between amother lower number, (it might be pretty difficult if you don’t know how to multiply though...)
Start by Rephrasing/re-ordering the equation (9/3 looks like 3*[?] =9)
1) Figure out what Factors equal 9 (by looking at a multiplication table or by adding up like described earlier)
2) You have your answer
(this took way too long to write and you’re probably an idiot if you’re actually in middle school...smh) I can write a different answer if you meant long division, or something else
