Hey there!
The unknown number will labeled as “p” until we find the actual answer
32 + p = 105
p + 32 = 105
SUBTRACT 32 to BOTH SIDES
p + 32 - 32 = 105 - 32
CANCEL out: 32 - 32 because that gives you 0
KEEP: 105 - 32 because it helps solve for the p-value (also known as the answer that is added to 32 to gives you 105)
p = 105 - 32
105 - 32 = p
p = 73
Therefore, your answer is: 73
Because 32 + 73 gives you 105
Good luck on your assignment and enjoy your day!
