20^2-12^2=256
400-144=256
sqrt 256 = 16
Answer:
D
Step-by-step explanation:
We put 2nd equation into 1st equation and get y:

We can't seem to come to a solution.
Also let's rearrange the 2nd equation into y = something form:
x = 7y + 1
7y = x - 1
y = 1/7 x -1
As we can see BOTH the lines have the same SLOPE, the number before x, which is 1/7 and we know that lines with same slope are parallel, they never intersect.
Having a solution to a system means their intersection point, since they are parallel lines, they don't intersect, and hence DO NOT HAVE A SOLUTION.
D is the correct choice.
