Whatever the variable was.
Thrice the same number.
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
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.
The number is -13.
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.

plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
-424Four times the unknown number
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
The same as a positive one. If you are multiplying a positive number by a negative, the answer will be negative. If you are multiplying a negative number by a negative, the answer will be positive.
