Question 1 Solve (x + 2y - 1)dax + (2x + y + 1)dy =0 O (y+1)2 +4 (x+ 1) (y +1) +(x+1) =0 O (y -1)' +4 (x + 1) (y - 1) +2(x+1)' =0 O (y-1)2 +2 (x+ 1) (y - 1) +(x+1)2 =0 O2(y -1)' +4 (x+1) (y - 1) + (x+1)' =0 O(y-1)' +4 (r+1) (y- 1) + (x+1)' =0 Question 2 Solve (2x + 1) dx - (x + 3y + 2) dy = 0 O (sty+ 1)'(4x - 6y + 1)* = C O (xty+1)? (4x - 3y + 1)3 = O(rty- 1)(4x - 6y - 1)3 = C O (rty - 1)' (4x - 6y + 1)3 = C O (sty+ 1)?(4x - 6y - 1)* = C
