Question

FAST РЕШИТЬ x(a+2)-a(1-x)=3

Answer 1

ax+2x-a+ax=3

2ax+2x-a=3

Answer 2

To solve the equation x(a+2)-a(1-x)=3, we can start by expanding the left-hand side:

cssCopy code
x(a+2) - a + ax = 3

Next, we can group the x terms and the constant terms:

cssCopy code
x(a + a) + 2x - a = 3

Simplifying further, we get:

cssCopy code
2ax + 2x = a + 3

Now, we can factor out 2x from the left-hand side:

cssCopy code
2x(a + 1) = a + 3

Finally, we can solve for x by dividing both sides by 2(a + 1):

cssCopy code
x = (a + 3) / 2(a + 1)

Therefore, the solution to the equation x(a+2)-a(1-x)=3 is x = (a + 3) / 2(a + 1).
