2x - 4 = 6x -4 = 4x x = -1
9+4x=2x-1 2x=-10 x=-5
sum - means addition less - means subtraction twice - means multiply by 2
2 x 20 = 40
Call your number some variable, for example, "n". Twice the number would be 2n, adding four to that you get 2n + 4, and six times all that is 6(2n + 4), which is the same as 12n + 24.
twice a number can be 2x and six less than it is 2x-6.
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
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
2x - 4 = 6x -4 = 4x x = -1
20
The equation would be as follows: 4x=2x-14 2x=14 x=7
9+4x=2x-1 2x=-10 x=-5

twice an unknown number less one and one-half times the same number equals two ---- Let the unknown number be "x":: Equation: 2x - (3/2)x = 2
X = number. 4X + 9 = 2X - 15 ===========
