Answer:
1
Step-by-step explanation:
2-x = 3-(7-3x)^0.5
-1-x = -(7-3x)^0.5
1+x = (7-3x)^0.5 // ()^2
(1+x)^2 = 7-3x
1+2x+x^2 = 7-3x
x^2+5x-6= 0
(x+6)(x-1) =0
x= 1,6
but you need to see if the solution solve it cause when you ()^2 the sequence you might add up another solution that isn't true. so if you'll see 6 doesn't solve it (try it) so the answer is 1
