Solve the pair of pair of equation for x and y respectively 2x-t - 3y-1 = 4, 4x-1 + y-1 = 1
Answer Details
2x-t - 3y-1 = 4, 4x-1 + y-1 = 1 Let x - 1 = a and y - 1= b 2a - 3b = 4 .......(i) 4a + b = 1 .........(ii) (i) x 3 = 12a + 3b = 3........(iii) 2a - 3b = 4 ...........(i) (i) + (iii) = 14a = 7 ∴ a = 714 7 14 = 12 1 2 From (i), 3b = 2a - 4 3b = 1 - 4 3b = -3 ∴ x = -1 From substituting, 2-1 = x - 1 ∴ x = 2 y-1 = -1, y = -1
