Question

Three times the sum of a number and 3 is the same as 1 subtracted from the number. Find the number.

Answer 1

-5

Explanation:

Let x be the number we are trying to find.

According to the problem statement, we know that:

3(x + 3) = x - 1

Expanding and solving for x, we get:

3x + 9 = x - 1

2x = -10

x = -5

So the number we were trying to find is -5.
