Answer:
- 22
Step-by-step explanation:
let the number be n then 2(n + 9) is the sum of the number and nine doubled, thus
2(n + 9) = n - 4 ← 4 less than the number
Distribute parenthesis
2n + 18 = n - 4 ( subtract n from both sides )
n + 18 = - 4 ( subtract 18 from both sides )
n = - 22
The number is - 22
