3 + 5p − 12 = 2p + 12

p=7

Step-by-step explanation: Pull out like factors :

  -21 + 3p  =   3 • (p - 7)   Solve  :    p-7 = 0  

Add  7  to both sides of the equation :  

                     p = 7

p=7

Step-by-step explanation:

Let's solve your equation step-by-step.

3+5p−12=2p+12

Step 1: Simplify both sides of the equation.

3+5p−12=2p+12

3+5p+−12=2p+12

(5p)+(3+−12)=2p+12(Combine Like Terms)

5p+−9=2p+12

5p−9=2p+12

Step 2: Subtract 2p from both sides.

5p−9−2p=2p+12−2p

3p−9=12

Step 3: Add 9 to both sides.

3p−9+9=12+9

3p=21

Step 4: Divide both sides by 3.

3p
