cos (3pi x/3) = 0.5
The number of answers depends on the range of angles. I will solve this question using the range 0<x<2 pi. Draw a unit circle, you will see that the quadrants where cosine gives a positive value are the first and the fourth quadrants.
The Angles whose cosines give + 0.5 are: pi / 3 and 5pi / 3. (Note that 7 pi/3 and 11 pi/3 are also possible solutions but they lie out of the range 0<x<2pi.)
3pi x/3 = pi/3 OR 3pi x/3 = 5pi/3
Here you can solve the equations to give x = 1/3; 5/3

Is the number 1 over 9 a solution to the equation 27x-5 equals 4?
No. The solution to the equation is 1/3. To solve: 27x - 5 = 4 (add 5 to each side to separate knownsa from inkowns) 27x = 9 (now divide both sides by 27 to find the value of x) x = 1/3 (solution)
