Answer:

3x + 6 = 12; Distributive Property

Step-by-step explanation:

3(x + 2) = 12

The next step is:

3*x + 3*2 = 12
3x + 6 = 12

This is a distributive property

Correct choice is A

How would I change this to standard form. <img src="https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20x%20-%201"

Answer:

x - 2y = 2

Step-by-step explanation:

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and A, B are integers )

given y = $\frac{1}{2}$ x - 1

multiply through by 2 to eliminate the fraction

2y = x - 2 ( subtract 2y from both sides )

0 = x - 2y - 2 ( add 2 to both sides )

x - 2y = 2 ← in standard form
