m in (-oo:+oo)
(3/8)*(m-(2/9)) = 43/4 // - 43/4
(3/8)*(m-(2/9))-(43/4) = 0
(3/8)*(m-2/9)-43/4 = 0
3/8*(m-2/9)-43/4 = 0
(3/8*4*(m-2/9))/4-43/4 = 0
3/8*4*(m-2/9)-43 = 0
3/2*m-130/3 = 0
(3/2*m-130/3)/4 = 0
(3/2*m-130/3)/4 = 0 // * 4
3/2*m-130/3 = 0
3/2*m-130/3 = 0 // + 130/3
3/2*m = 130/3 // : 3/2
m = 130/3/3/2
m = 260/9
m = 260/9
