What is equivalent to x +1 over x-1

What is the value of x in the equation 1.5x+4-3=4.5(x-2)?

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.

For a function f(x), a) if f(7) = 22 then f^-1(22) = b) f^-1(f(c)) =
