Let x = "a certain number"
:
Three times the result of subtracting a certain number from 5 gives the same answer as dividing the number by 3.
3(5-x) = x%2F3
Multiply both sides by 3, results:
3*3(5-x) = x
9(5 - x) = x
45 - 9x = x
45 = x + 9x
45 = 10x
x = 45%2F10
x = 4.5 is the number

Check solution in the statement:
"Three times the result of subtracting a certain number from 5 gives the same answer as dividing the number by 3."
3(5 - 4.5) = 4.5/3
3(.5) = 1.5
