It is known that (m-1) x - (M + 1) x + 8 = 0 is a linear equation of one variable with respect to X, Find the value of 200 (M + x) (x-2m) + M

It is known that (m-1) x - (M + 1) x + 8 = 0 is a linear equation of one variable with respect to X, Find the value of 200 (M + x) (x-2m) + M

It is known that: M-1 = 0, and M + 1 ≠ 0, so M-1 = 0, that is, M = 1 is substituted into the original formula to get: - 2x + 8 = 0, that is, x = 4. So, 200 (M + x) (x-2m) + M = 200 × (1 + 4) × (4-2) + 1 = 2001. Question: what grade are you in? Answer: I have worked for many years

When x is less than 0, x = 8 is a linear equation with one variable, and its solution x = ()

∵X＜0
∴X/3＜0
And ∵ 8 > 0
The equation has no solution in the range of real number
∵ equation = 8
The equation has no solution in the range of imaginary number
To sum up, the equation has no solution

How to solve the requirement process with 0.4x + 0.8 (20-x) = 10

0.4X+0.8（20-X)=10
0.4x+0.8×20-0.8x=10
（0.8-0.4）x=16-10
0.4x=6
x=6÷0.4
x=15
