a number is decreased by 3 is at least four times the number
To find the number that satisfies the condition, we can use algebraic notation.
Let's represent the number as "x". According to the condition stated, when this number is decreased by 3, it is at least four times the original number.
We can express this condition with the following inequality:
x - 3 ≥ 4x
To find the value of "x", we can solve this inequality:
x ≥ -3
Thus, any value of "x" that is greater than or equal to -3 satisfies the given condition. For example, x = -2, -1, 0, 1, etc.
n-3 >/= 4 n ????
3 n </= -3
n </= -1
===============
check, try n = -2
-2 -3 >/= 4 (-2)
-5 >/= -8
yes, -5 is to the right of -8 on number line.
