Solution for 3r/4-(2r-1)/8=3/2 equation: 


r in (-oo:+oo)

(3*r)/4-((2*r-1)/8) = 3/2 // - 3/2

(3*r)/4-((2*r-1)/8)-(3/2) = 0

(3*r)/4-((2*r-1)/8)-3/2 = 0

(-1*(2*r-1))/8+(3*r)/4-3/2 = 0

(-1*2*4*(2*r-1))/(2*4*8)+(2*3*8*r)/(2*4*8)+(-3*4*8)/(2*4*8) = 0

2*3*8*r-1*2*4*(2*r-1)-3*4*8 = 0

32*r-96+8 = 0

32*r-88 = 0

(32*r-88)/(2*4*8) = 0

(32*r-88)/(2*4*8) = 0 // * 2*4*8

32*r-88 = 0

32*r-88 = 0 // + 88

32*r = 88 // : 32

r = 88/32

r = 11/4

r = 11/4
