A number x is at least -10: X ≥ -10
X is *at least* -10, meaning that it will either be that or something greater.
Twice a number y is more than 5/2:
2y > 5/2
Two times y is the same as writing 2y. It says that this is greater than 5/2, thus the greater than sign.
Hope this is right and it helps :)
There is only one solution since x=0 x cant be many things since the only thing that would make this true is 0
(1+i)/(1-i)
(1+i)/(1-i) • (1+i)/(1+i)
(1+i)(1+i)/(1-i)(1+i)
(1+2i+i^2)/(1+i-i-i^2)
(1 + 2i - 1)/(1 - i^2)
(2i)/(1 - (-1))
(2i)/(1 + 1)
2i/2
i
