-2 is the solution of the following one variable linear equation: A, 2x + 6 = 2 B, x + 7 of 4 = - 6 and 1 / 2 C, x 2 of 2 + 2 of 2 = - 2

AC

Given that (M-3) x | m-2 | - 3M = 0 is a linear equation of one variable with respect to x, then M=______ ．

∵ (M-3) x|m-2 | - 3M = 0 is a linear equation of one variable about X, ∵ |m-2 | = 1 and M-3 ≠ 0, ∵ m-2 = ± 1 and m ≠ 3, ∵ M = 1

It is known that a is a negative number, which is reduced to | - A + | - 2A | - 4-a2

∵ a ＜ 0, the original formula = | - a − 2A | 4-a2 = - 3a4-a2 = - 5A4

It is known that the equation (A-4) x | a | - 3 + 2 = 0 is a linear equation with one variable?

If it is a linear equation of one variable, then the degree of X is 1 and the coefficient of X is not equal to 0
|a|-3=1
|a|=4
a=±4
a-4≠0
a≠4
So a = - 4
