Question

If 2021 + x = 2020, then what is 3x + 1?

Answer 1

3x+1 is -2
because if 2021+x=2020 then you go one down so x=-1 and -1 times 3 is -3. -3+1=-2

Answer 2

Explanation:

In order for you to add x to 2021 and get 2020, x has to be -1

2021 + (-1) = 2020

Then, you reapply the value of x to the new equation

3x + 1 now become 3(-1) + 1

3(-1) + 1 = -2
