Mọi ng giải giúp e b1 vs ạ. Trừ ý 2

cho hàm số y=(m+1) x -3m+1 a, tìm m để (d) song song với đường thẳng y =-x-2 b, tìm m để (d) cắt đt y=x-1 tại 1 điểm có tung độ bằng -1

bài 1 : a, y x 45 + y x 55 = 1000 b, ( y - 1/2 ) x 5/3 = 7/4 - 1/2 c, y - 6 : 2 - ( 48 -24 x 2 : 6 - 3 ) = 0 d, ( 7 x 13 + 8 x 13 ) : ( 9 $\dfrac{2}{3}$ - y ) = 39
