Answer:
x = 0
Step-by-step explanation:
= 2 - x ( square both sides to clear the radical )
x + 4 = (2 - x)² ← expand using FOIL
x + 4 = 4 - 4x + x² ( subtract x + 4 from both sides )
0 = x² - 5x ← factor out x from each term
0 = x(x - 5)
equate each factor to zero and solve for x
x = 0
x - 5 = 0 ⇒ x = 5
As a check
substitute these values into the equation and if both sides are equal then they are the solutions
x = 0
left side = = = 2
right side = 2 - 0 = 2
then x = 0 is a solution
x = 5
left side = = = 3
right side = 2 - 5 = - 3 ≠ 3
then x = 5 is an extraneous solution

<span>8,241 divided by 173 equals 47 and 110/173. You get this by figuring out how many times 173 can fit into 8,241 evenly, then you are left with a remainder that is smaller than 173. The remainder is put into a fraction, being 110 left, out of the total of 173.</span>
Answer: x = -1
Step-by-step explanation:
i assume you mean
5x-(5x+3) = -1/3(12x+21)
lets start with the left
-(5x+3) can be turnd into -5x-3
now it is
5x-5x-3 and that can be just -3
now lets go to the right and get rid of the 1/3
we see the 3 at the bottom of 1/3, and (12x+21) can be factored with 3
so 1/3 x 3(4x+7) is what we get
1/3 x 3 cancels out so we are left with
-3 = (-4x-7)
lets try to get -4x by itself
if you move -4x to the left, turning it into 4x, and move -3 to the right, turning it into 3, you get 4x = -7 +3
-7 +3 = -4
4x = -4
devide by 4
4x/4 = -4/4
x = -1
