 7. Graphical Method Solve linear equations 12x+5y=7 and x+y=7 using Graphical Method12x+5y=7x+y=7The point of intersection of the linear equationsConsider 12x+5y=7x-intercept: put y = 0, we get x = 0.5833 :. A(0.5833,0)y-intercept: put x = 0, we get y = 1.4 :. B(0,1.4)Consider x+y=7x-intercept: put y = 0, we get x = 7 :. C(7,0)y-intercept: put x = 0, we get y = 7 :. D(0,7)Intersection Point = P(-4,11)
