Then the number is 3
To solve the equation "twice the number plus seven is equal to three less than four times the number," we can express it mathematically as ( 2x + 7 = 4x - 3 ). By rearranging the equation, we get ( 7 + 3 = 4x - 2x ), leading to ( 10 = 2x ). Dividing both sides by 2 gives ( x = 5 ). Thus, the number is 5.
7
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.
2x - 7 = -1
The number is 7.
If the number is N then 2N - 5 = 7 then 2N = 12 so that N = 6
This forms an equation which solves nicely: 2x-7 = x-1 x-7 = -1 x = 6
5+5=1010-7=3the answer is 3

The greatest prime number less than 20 is 19. Not sure what "then twice" is unless you are wanting to double it, which becomes 38.
2x + 7 = 15 Subtract 7 from both sides: 2x = 8 Divide both sides by 2: x = 4
the equation is 2x + 4 = x - 3 solving it yields x = -7
