This means that X=2N-3.
sum - means addition less - means subtraction twice - means multiply by 2
2n - 2
2x-3
2k - 7
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.
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
sum - means addition less - means subtraction twice - means multiply by 2
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.
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
20
15
2n - 2
2x - 2
um, 9.
if a number is "x" then it is 2x-16
The number is -6.
