Answer:
The equation: 2n - 3 ≤ -21
The answer to the equation: n ≤ 9
Step-by-step explanation:
How to get the equation:
The difference of symbolizes subtraction. Because we are subtracting twice a number and 3, the first part of the equation can be written as 2n - 3. The n symbolizes the number.
is at most symbolizes a less than or equal to sign. That sign is ≤. And what is it less than or equal to? -21.
Now are equation is 2n - 3 ≤ -21
How to solve it:
2n - 3 ≤ -21
Add 3 to both sides of the equation
2n ≤ 18
Divide both sides of the equation by 2
n ≤ 9
