hello
to solve this question, we should let the unknown number be represented by x
[tex]\begin{gathered} x+2x=33 \\ 3x=33 \\ \text{divide both sides by the coefficient of x} \\ \frac{3x}{3}=\frac{33}{3} \\ x=11 \end{gathered}[/tex]the first number (x) is equal to 11, we can find the other number.
[tex]2x=2\times11=22[/tex]from the calculations above, the numbers are 11 and 22
