Answer:
-20.67
Step-by-step explanation:
Let the number be represented = x
Seven times the sum of a number and six subtracted from four times the number results in negative twenty
7 ×(x + 6) - 4 x x = -20
7(x + 6) - 4x = -20
7x + 42 - 4x = -20
7x - 4x = -20 - 42
3x = -62
x = -62/3
x = -20.67
The number is -20.67
