Answer 1

Answer:

-2/3= x

Step-by-step explanation:

square all the terms on both sides to get rid of the radicals:

$1^{2} + (\sqrt{1-x} )^{2} = (\sqrt{2x+4}) ^{2}$

exponent 2 and the radical cancel each other:

1 + 1 - x = 2x + 4

2 - x = 2x + 4

like terms on each side ( when you move one term tp the other side, it changes its sign ):

2-x = 2x+4

2-4 = +x +2x

-2 = 3x

now to keep the x alone, divide both sides by 3:

-2/3 = 3x/3

-2/3= x
