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.
2x - 4 = 6x -4 = 4x x = -1
Whatever the variable was.
9+4x=2x-1 2x=-10 x=-5
Let's call the number XTwice the number would be 2XFour times the same number would be 4XThe sum of these two is 2X + 4X = 6XThe answer is therefore six times the number.
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
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.
2x - 4 = 6x -4 = 4x x = -1
The equation would be as follows: 4x=2x-14 2x=14 x=7
The answer is 42
Whatever the variable was.
9+4x=2x-1 2x=-10 x=-5
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
18
twice a number can be 2x and six less than it is 2x-6.
Let's call the number XTwice the number would be 2XFour times the same number would be 4XThe sum of these two is 2X + 4X = 6XThe answer is therefore six times the number.
Let's name the first number "X" and the other number "Y" thus: 2X+5Y is the same thing as twice a number more than five times another
