Answer:
Step-by-step explanation:
let n be the missing number.
1. pag inadd daw ang 13 sa isang number, 5 ang sagot.
13 + n = 5
n = 5-13
n = -8
2. pag ang 12 daw ay binawas sa twice nung number, sagot ay 24.
2n - 12 = 24
2n = 24+12
2n = 36
divide both sides by 2
n = 18
3. six times a number and seventeen = 6n + 17 (sum, kaya addition ang operation)
thrice the number = 3n
thrice the number increased by two = 3n + 2
6n + 17 = 3n + 2
-3n + 6n = -17+2
3n = -15
divide both sides by 3
n = -5
