I will brainlist who can answer this all! Determine whether each linear system has one solution, no solution, or an infinite number of solutions.

4) has one solution which is :
x= -67/59 y= - 115/59

5) has no solution

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
