We'll call the unknown number "n."
Four more than two thirds of a number is 22.
Four more than (two thirds of a number) is 22.
4 + (two thirds of a number) = 22
4 + ([tex] \frac{2}{3} [/tex] * n) = 22
Now, we solve.
4 + ([tex] \frac{2}{3} [/tex] * n) = 22
4 + ([tex] \frac{2}{3} [/tex] * n) - 4 = 22 - 4
([tex] \frac{2}{3} [/tex] * n) = 18
([tex] \frac{2}{3} [/tex] * n) / ([tex] \frac{2}{3} [/tex]) = 18 / ([tex] \frac{2}{3} [/tex])
n = 18 * ([tex] \frac{3}{2} [/tex])
n = 27
Hope this helps! :)
