solve this problem.
and say if they are independent, dependent, or inconsistent.
The two problems go together.
5x = y - 7
20x = 4y
--------------------------
Put the equations in slope-intercept form.
y = 5x + 7
y = 5x
-----------------
The lines have the same slope, so are parallel.
The lines are inconsistent.
