Answer:
when z=3 or 5 , values of x is ; 6 or 10.
I think that there is a lack of information or misspelling in the question.
Step-by-step explanation:
4x-3=6x-4z-3
4z=2x
2z=x
z=3 => x=6
z=5 => x=10
First you would find the difference of 210 and 46, so 210-46=164.
Then you will divide the solution by the total number of students, so
164 divided by 210.
164/210= about .780 or 78%
