Hi, first make 2 equations from 4x - y = 6 and 2x -5y =12... 4x - y = 6 ------(1) 2x - 5y = 12 -----(2) Now .. solve them taking them as a system of equation ... and the values u get by solving them r coordinates of the intersection point of those 2 lines.. (2) x 2 4x -10y =24 -----(3) (3) - (1), 4x -y - [ 4x -10y ] = 18 9y = 18 y = 2 and substitute y = 2 in (1), 4x - y = 6 4x = 6+y 4x = 8 x = 2 So ... the intersection point of those 2 lines r (2,2) now if the function y = p-3x passes through that lpoin then the co-ordinates (2,2) should satisfy the function.. which mean.. 2 = p - (3x2) p = 8 yep !! that's it.. Hope this will help ya!!!
