Question

I think of a number, treble it and take 6 from my answer. If the result is 18, find the number. My teacher says its 4 I say its eight whats the answer?

Answer 1

Answer: Let's work through the problem step by step:

"Treble it": If we call the unknown number "x", then "trebling" it means multiplying it by 3, so we have 3x.

"Take 6 from my answer": We subtract 6 from 3x, giving us 3x - 6.

"If the result is 18": We set 3x - 6 equal to 18 and solve for x.

So, we have:

3x - 6 = 18

Adding 6 to both sides:

3x = 24

Dividing both sides by 3:

x = 8

Therefore, the answer is 8.
