Answer :

The unknown number in the equation 5x + 21 = 141 is 24. This was found through isolating the term with x and solving the equation.

The subject of this question is Mathematics. Here, we're being asked to work with an algebraic equation. The problem states that the product of 5 and an unknown number, which is increased by 21, is equal to 141. We can represent this situation with the equation 5x + 21 = 141.

Let's solve for x:

First, to isolate the term with x, we subtract 21 from both sides of the equation: 5x = 141 - 21;

This gives 5x = 120;

Next, we solve for x by dividing both sides of the equation by 5: x = 120 / 5;

Hence, x = 24;

So, the unknown number in the question is 24.
