The line l1 l_1\,l1 has the equation 3x+y−5=03x + y - 5 = 03x+y−5=0 The line l2 l_2\,l2 has the equation x−y−1=0x - y - 1 = 0x−y−1=0
Write down the simultaneous equations that can be used to find the point where l1 l_1\,l1 and l2 l_2\,l2 intersect.
Hence find the coordinates of the point where l1 l_1\,l1 and l2 l_2\,l2 intersect.
