How

OpenStudy (anonymous):

15x-3x=12 12x=120 x=120/12 x= 10

OpenStudy (anonymous):

\[15x=3x+120\] subtract 3x from both sides gives \[15x-3x=3x-3x+120\] \[12x=120\] divide both sides by 12 gives \[\frac{12x}{12}=\frac{120}{12}\] \[x=10\]

OpenStudy (anonymous):

you subtract 3x from both sides so 15x-3x =12x 12x=120 x= 10 it's simple dividing
