2X = 5X - 150 3X = 150 X = 50 The number is 50.
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
Oh, dude, so you want me to do some math for you? Alright, let's break it down. Twice the number 50 is 100, right? And 20 less than 100 is 80. So, 20 less than twice the number 50 is 80. Boom, math wizard right here!
Any negative number.
the equation is 2x + 4 = x - 3 solving it yields x = -7
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
Twenty more than twice a number is 52
10
The number is 7.
2x = 3x - 22x - 3x = -2-x = -2x = 2Therefore, the number is 2.
the quotient of twice a number and six is.... 2x/6 four less than three times the same number is .... 3x-4 So the equation would be 2x/6=3x-4
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.
14 more then a number cubed minus twice the number
X = number. 4X + 9 = 2X - 15 ===========
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
6n - (2n + 10 - 5)
