3,666 = 39(p +25)<br><br> 20 POINTS + BRANLIESTTT PLEASE HELP
iVinArrow [24]

Answer:p=69

Step-by-step explanation:

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

3666=39(p+25)

Step 1: Simplify both sides of the equation.

3666=39(p+25)

3666=(39)(p)+(39)(25)(Distribute)

3666=39p+975

Step 2: Flip the equation.

39p+975=3666

Step 3: Subtract 975 from both sides.

39p+975−975=3666−975

39p=2691

Step 4: Divide both sides by 39.

39p /39  =  2691 /39
