Let the unknown number be x:
x-4 = 2x
-4 = 2x-x
-4 = x
So the number is -4
2x - 4 = 6x -4 = 4x x = -1
The sum of four times a number and twice the same number can be represented mathematically as (4x + 2x), where (x) is the number. Combining the terms, this simplifies to (6x). Therefore, the result is six times the number.
9+4x=2x-1 2x=-10 x=-5
sum - means addition less - means subtraction twice - means multiply by 2
2 x 20 = 40
Nine less than twice a number equals the same number increased by four?
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 a number can be 2x and six less than it is 2x-6.
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 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 ===========
