Answer:
The resultant expression would be 22 - 12x
Step-by-step explanation:
Let x be the unknown number,
Six plus four times a number = 6 + 4x
Four times four minus four times the number number = 4(4 - 4x)
Thus, Six plus four times the number plus four times four minus four times the number number = 6 + 4x + 4(4 - 4x)
Using distributive property,
6 + 4x + 16 - 16x
Combining like terms,
22 - 12x
