Let x be the unknown number. the expression is: x + 10.
x = 14
10
...so the number is 10 less than 16. Can you work it out now...?
It is: 10+(-1) = 9
3x+30let x = "a number"(x+10) = "a number increased by 10"3(x+10) = "3 times a number increased by 10"Expand: 3x+30

"Still" implies that the original number is a square number. In that case, the answer is as follows: There is no number such that it is a perfect sqiuare and that the number increased (or decreased) by 10 is also a perfect square. And if you do not limit it to perfect square then every non-negative number is a square with the number that is 10 more also being a square.
It is: 10+(-1) = 9
01-x
15. 5 - -10 = 5 + 10 = 15 → 15 + -10 = 15 - 10 = 5
If the number is x then: 4x+10 = -2 and so the value of x is -3
2 -> 9 = +79 -> 5 = -45 ->13 = +813 -> 10 = -310 -> 19 = +919 -> 17 = -2As you can see, every other time, the number is increased. It was originally increased by 7, then 8, then 9. So, the next number should be increased by 10 = 27
