Question

Write and solve the inequality: Sixty-three is at most triple the difference of double a number and three​

Answer 1

Answer: n=30

Explanation:

first, you subtract 3, as 'and' refers to addition and the opposite is subtraction. this gives you 60.

then you divide by 2, which gives you 30.

if you want, you can input 30 into the equation the situation creates, which is 63 = 2n + 3. input 20 makes 2(30) + 3, which is 60 + 3, which is 63.
