In expression x-2 coefficient of x is equal to one. Let a be "a" x's coefficient. If we put "a" to Your equation, it should be looks like: ax-2 We know that there is only one x, so expression ax have to be equal x Now we get a x = x From this equation we know that coefficient x "a" is equal to 1.
it is assumed that the coefficient of x in x-2 is 1 because there is 1 x. if the question read 2x-2 then there is 2 x's. the answer is 1
The coefficient of x in the expression x − 2 is 1 because the term can be rewritten as 1 ⋅ x .
