x in (-oo:+oo)

((7-x)^1)/2 = ((2*x+13)^1)/2 // - ((2*x+13)^1)/2

((7-x)^1)/2-(((2*x+13)^1)/2) = 0

(7-x)/2-((2*x+13)/2) = 0

(7-x)/2+(-1*(2*x+13))/2 = 0

7-1*(2*x+13)-x = 0

(-2-1)*x-13+7 = 0

((-2-1)*x-13+7)/2 = 0

((-2-1)*x-13+7)/2 = 0 // * 2

(-2-1)*x-13+7 = 0

(-2-1)*x-13+7 = 0 // - 7-13

(-2-1)*x = -(7-13) // : -2-1

x = (-(7-13))/(-2-1)

x = (13-7)/(-2-1)

x = (13-7)/(-2-1)
