Answer:

Step-by-step explanation:

When we use the distributive property for expanding polynomial products, we often use it in the form ...

(a +b)c = ac +bc

Here, we have ...

(a +b) = (x -1) ⇒ a=x, b=-1

c = (4x+2)

So, the proper application of the distributive property looks like ...

(a +b)c = ac +bc

(x -1)(4x +2) = x(4x+2) -1(4x+2) . . . . . different from the work shown

We must conclude ...

The distributive property was not applied correctly in the first step.

Answer:

a linear equation in x and y

Step-by-step explanation:

The given equation is a linear equation (all variables to the first power) relating the variables x and y. There are an infinite number of values of x and y that will satisfy this equation.

When graphed on an x-y plane, those solution values will fall on a straight line with a slope of 2. It will cross the y-axis at y=32, and the x-axis at x=-16.
