t in (-oo:+oo)
t-((5*t-7)/2) = 3/4 // - 3/4
t-((5*t-7)/2)-(3/4) = 0
t-((5*t-7)/2)-3/4 = 0
(-1*(5*t-7))/2+t-3/4 = 0
(-1*4*(5*t-7))/(2*4)+(2*4*t)/(2*4)+(-3*2)/(2*4) = 0
2*4*t-1*4*(5*t-7)-3*2 = 0
28-12*t-6 = 0
22-12*t = 0
(22-12*t)/(2*4) = 0
(22-12*t)/(2*4) = 0 // * 2*4
22-12*t = 0
22-12*t = 0 // - 22
-12*t = -22 // : -12
t = -22/(-12)
t = 11/6
t = 11/6
