What plus what plus what equals 21?

Answer 1

x=3

actually its 7

Answer 2

Well... assuming that you mean x + x + x = 21, x would be 7. But if its x + y + z = 21, there would be an astounding amount of answers. So, the answer that I would give that is the most specific would be that 7 plus 7 plus seven equals 21.

9 + 10

Answer 4

Well, honey, if you're not the brightest bulb in the box, it's pretty simple. Just add 7 + 7 + 7 and voila, you've got yourself a nice, neat 21. Math can be a real piece of cake sometimes, don't you think?

Answer 5

To solve the equation "x + y + z = 21," we must consider all possible combinations of three numbers that add up to 21. One example is 5 + 8 + 8 = 21. Another solution could be 6 + 7 + 8 = 21. There are multiple combinations that satisfy this equation, making it important to explore all possibilities.

Answer 6

Oh, dude, math time! Let's see, if we add 7 to 7 to 7, we get 21. So, like, 7 + 7 + 7 = 21. Ta-da! Math wizardry at its finest.
