See that graphic I have two equations and 2 incognitos, see each equation draw one graphic that is a line because they are of 1st grade, all the two have a range of numbers but they intersect in one point soo seing the graphic I even don't need solve the question, the intersection is the value of x and y for the 2 equation the intersection is (1,6) meanins (x, y) so x = 1 and y = 6.
The diference of me and another I saw and realize without nobody say I saw and was convincing who was at my side, but if you want solve, go ahead.
