Solution for z-3/4z+3/8=-3/8(z-7/2) equation: 


z in (-oo:+oo)

z-((3/4)*z)+3/8 = (-3/8)*(z-(7/2)) // - (-3/8)*(z-(7/2))

z-((-3/8)*(z-(7/2)))-((3/4)*z)+3/8 = 0

(3/8)*(z-7/2)+z+(-3/4)*z+3/8 = 0

3/8*(z-7/2)+z+(-3*z)/4+3/8 = 0

(3/8*4*8*(z-7/2))/(4*8)+(4*8*z)/(4*8)+(-3*8*z)/(4*8)+(3*4)/(4*8) = 0

3/8*4*8*(z-7/2)+4*8*z-3*8*z+3*4 = 0

44*z-24*z-42+12 = 0

20*z-42+12 = 0

20*z-30 = 0

(20*z-30)/(4*8) = 0

(20*z-30)/(4*8) = 0 // * 4*8

20*z-30 = 0

20*z-30 = 0 // + 30

20*z = 30 // : 20

z = 30/20

z = 3/2

z = 3/2
