Its 11
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
If a number is increased by 20 and then decreased by 20, the final value remains the same as the original number. This is because the two operations effectively cancel each other out. Therefore, the final value is equal to the original number.
6+n = 2n+5
x+5 = 7 - (2x) 3x = 2 x = 2/3 The number is 2/3
x - 2 = 7 + x/4 4x - 8 = 28 + x 3x = 36 x = 12
The difference between a number x and twice y is equal to fifteen.

Expressed algebraically, this is equal to x - 92.
How do you write half a number decreased by 8 is equal to the sum of the number and 14
