Answer:
-2/3= x
Step-by-step explanation:
<u><em>square all the terms on both sides to get rid of the radicals:</em></u>
<u><em>exponent 2 and the radical cancel each other:</em></u>
1 + 1 - x = 2x + 4
2 - x = 2x + 4
<u><em>like terms on each side ( when you move one term tp the other side, it changes its sign ):</em></u>
2-x = 2x+4
2-4 = +x +2x
-2 = 3x
<u><em>now to keep the x alone, divide both sides by 3:</em></u>
-2/3 = 3x/3
-2/3= x
