Answer 1

Объяснение:

(х-1)-а(1-х)=х-1-а+ах

Answer 2

It seems like you want to solve the equation (x-1)-a(1-x) = 10 for the variable x. To do this, we'll first simplify the equation and then solve for x.

Let's start by simplifying the equation:

(x - 1) - a(1 - x) = 10

Now, distribute the -a on the right side:

x - 1 - a + ax = 10

Next, group like terms:

x + ax - 1 - a = 10

Now, let's collect the terms with x:

x(1 + a) - (1 + a) = 10

Now, factor out (1 + a):

(1 + a)(x - 1) = 10

Now, we can isolate x by dividing both sides by (1 + a):

x - 1 = 10 / (1 + a)

Now, add 1 to both sides to solve for x:

x = 10 / (1 + a) + 1

So, the solution for x in terms of 'a' is:

x = (10 + 1 + a) / (1 + a)

Simplified further:

x = (11 + a) / (1 + a)

That's the solution for x in terms of 'a'.
