## Re: 3x + y = 4(2-z)

3x + y = 4(2-z)...Solve for x.

Subtract y from both sides. By doing so, you will isolate the term 3x.

3x = 4(2 - z) - y

We now divide both sides by the coefficient of x, which is the number 3.

**x = [4(2 - z) - y]/3**

By the way, you can use the distributive rule in terms of**4(2 - z)**to simplify further if needed.
