A system of linear equations will have no solution when the two lines making up the equation are parallel. Here, a system having x + y = 2 will have no solution if the second equation is x + y = a. where a is any real number.
Since this is an equilateral traingle, as indicated with the marks on every side, you can set each equation equal to 60.
7x-3=60
7x=63
x=9
