2k - 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.
2x - 7 = -1
The number is 7.
If the number is N then 2N - 5 = 7 then 2N = 12 so that N = 6
x / (2y - 7)
5+5=1010-7=3the answer is 3
2n-3=(-7) 2n=-4 n=-2
2x + 7 = 15 Subtract 7 from both sides: 2x = 8 Divide both sides by 2: x = 4
This forms an equation which solves nicely: 2x-7 = x-1 x-7 = -1 x = 6
twice a number can be 2x and six less than it is 2x-6.
2x + 7
Let the number be x and so if 2x -7 = 15 then the value of x is 11
Nine less than twice a number equals the same number increased by four?
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).
if the product of a number and -7 is reduced by 3, the result is 33 less than twice the opposite of the number. What is the number?
the equation is 2x + 4 = x - 3 solving it yields x = -7
if a number is "x" then it is 2x-16
Then the number is 3
