+ or - 11
Step-by-step explanation:
To find the square root of 121, think of a number that multiplied by itself would get to 121. This number is 11. However, do remember that the number could also be negative 11 bencause a negative times a negative becomes positive. I would advise you to try memorizing the squares of 0 to 15 to help you with this. Otherwise, you can just use a calculator.

Answer:
- 45
Step-by-step explanation:
let n be the number , then
n - 11 = n + 4 ( add 11 to both sides )
n = n + 15 ( multiply through by 3 to clear the fraction
2n = 3n + 45 ( subtract 2n from both sides )
0 = n + 45 ( subtract 45 from both sides )
- 45 = n
The number is - 45
