Answer:
13
Step-by-step explanation:
let x be the number
write the equation and solve:
x + 15 = 28
x = 28 - 15
x = 13
to prove the answer;
x + 15 = 28
13 + 15 = 28
28 = 28
the answer is correct.
para mas madali po, subtract mo nalang yung 28 sa 15, ginawa ko lang yan incase need ng matinong solution. pakicorrect nalang po if may mali (〃ﾟ3ﾟ〃)
