x in (-oo:+oo)

(12-(7*x))/6 = (2*x+1)/9 // - (2*x+1)/9

(12-(7*x))/6-((2*x+1)/9) = 0

(12-7*x)/6-((2*x+1)/9) = 0

(12-7*x)/6+(-1*(2*x+1))/9 = 0

(9*(12-7*x))/(6*9)+(-1*6*(2*x+1))/(6*9) = 0

9*(12-7*x)-1*6*(2*x+1) = 0

102-75*x = 0

(102-75*x)/(6*9) = 0

(102-75*x)/(6*9) = 0 // * 6*9

102-75*x = 0

102-75*x = 0 // - 102

-75*x = -102 // : -75

x = -102/(-75)
