The one on the left is -5/6
The one on the right is 1/21
I think its 36
Hope this helps sorry if im wrong
It would be -8/10 because
16/20 when simplified is 8/10
4/5 when doubled is 8/10
-8/-10 is still 0.8 which is also 8/10 (-8 divided by -10 = 0.8)
When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.
