x in (-oo:+oo)

4*(x-1)+4/9 = 7*x-x+31/9+1 // - 7*x-x+31/9+1

4*(x-1)+x-(7*x)+4/9-(31/9)-1 = 0

4*(x-1)+x-7*x+4/9-31/9-1 = 0

(4*9*(x-1))/9+(9*x)/9+(-7*9*x)/9+4/9-31/9+(-1*9)/9 = 0

4*9*(x-1)+9*x-7*9*x-1*9-31+4 = 0

45*x-63*x-36-31-9+4 = 0

4-18*x-36-31-9 = 0

-18*x-32-31-9 = 0

-18*x-63-9 = 0

-18*x-72 = 0
