x in (-oo:+oo)
7-(5*x)+12 = (1/3)*(4*x+60) // - (1/3)*(4*x+60)
7-((1/3)*(4*x+60))-(5*x)+12 = 0
(-1/3)*(4*x+60)-5*x+7+12 = 0
7-1/3*(4*x+60)-5*x+12 = 0
7-1/3*(4*x+60)-5*x+12 = 0
7-19/3*x-20+12 = 0
12-19/3*x-13 = 0
-19/3*x-1 = 0
-19/3*x-1 = 0
-19/3*x-1 = 0 // + 1
-19/3*x = 1 // : -19/3
x = 1/(-19/3)
x = -3/19
x = -3/19
