Six plus four times a number plus four times four minus four times the number no
zalisa [80]

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
