It is known that (M2-1) X2 - (m-1) x + 8 = 0 is a linear equation of one variable with respect to x, and its solution is n (1) Find the value of the algebraic formula 200 (M + n) (n-2m) - 3M + 5 (2) Finding the solution of the equation m y = n about y

m²-1=0
m-1≠0
∴m=-1
When m = - 1, the equation is 2x + 8 = 0
∴x=-4
∴m|y|=n
-|y|=-4
y=±4
Typing is not easy,
