The first step for solving this problem is to multiply both sides of the bottom equation by -3.
Add the two equations together.
6x - 9y - 6x + 9y = 16 - 21
Eliminate the opposites.
-9y + 9y = 16 - 21
Remember that the sum of two opposites equals 0,, so the equation becomes the following:
0 = 16 - 21
Calculate the difference on the right side of the equation.
0 = -5
This means that the statement
is false for any value of x and y. That means that the answer to your question is (x,y) ∈ ∅,, or no solution.

Answer: (f + 2) (f + 8)
It's hard to explain, but I suggest you use the AC method. Hope this helps!
Answer:
y=1x+2 or y=x+2
Step-by-step explanation:
We know that the slope is going to be one since the slopes of parallel lines are equal and the other equation has a slope of 1. We can then use the equation y=1x+b and the point given, (2,4), to find the y-intercept, b. You plug in (2,4) as your x and y values to get 4=1(2)+b. You can then solve this by multiplying to get 4=2+b, then subtracting 2 from both sides to get b=2. We can then use b to complete the equation as y=1x+2 or y=x+2.
