Answer :
[tex]60x+153=9x+51\ \ \ subtract\ 153 and 9x \ to\ both\ sides \\\\ 60x-9x+153-153=9x-9x+51-153\\\\51x = -102\ \ | \ divide \ both \ sides\ by\ 51 \\\\x=-\frac{102}{51}\\\\x=-2[/tex]
60x+153=9x+51
60x-9x=51-153
51x=51-(51+51+51)
51x=51-51-51-51
51x=-102
x=(-102)/51
x=-2
60x-9x=51-153
51x=51-(51+51+51)
51x=51-51-51-51
51x=-102
x=(-102)/51
x=-2
