Question

Twice the difference of a number and 6 is greater than 20

Use the variable X for the unknown number

Answer 1

Step-by-step explanation:

x = the number

(x-6)×2 > 20

2x - 12 > 20

2x > 32

x > 16

this is true all x of the interval (16, +infinity). both ends not included (because x > 16, x = 16 is not included).
