you r asking a number whose twice will be 4 but less than 8.
so,
take a no. x.
by ques. 2x=4;
2x=4;
x=4/2;
hence x=2;
2 is answer and less than 8 of twice it.
3*(n - 5) = 2*n + 11
it means multiplying the original number by two and then subtracting two, like if your original number was 10, 10 times two equals 20 minus 4 equals 16.
2n - 2
2x-3
2k - 7
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
3*(n - 5) = 2*n + 11
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7This could also be a boolean variable based on another variable. If the number is less than or equal to 3.5, the variable is false. Otherwise, it is true.
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
2x + 5 =
it means multiplying the original number by two and then subtracting two, like if your original number was 10, 10 times two equals 20 minus 4 equals 16.
