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 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.
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
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 number is -13.
The answer is 42
18
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

It is 0.722... recurring.
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.
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
