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.

PLZ MARK ME BRAINLIEST..
I'm pretty sure x = 6 and y = 10
4 * 6 + 3 * 10 = 54
24 + 30 = 54
3 * 6 + 9 * 10 = 108
18 + 90 = 108
