15x+35=15\left(x+4\right)-25
Combine 6x and 9x to get 15x.
15x+35=15x+60-25
Use the distributive property to multiply 15 by x+4.
15x+35=15x+35
Subtract 25 from 60 to get 35.
15x+35-15x=35
Subtract 15x from both sides.
35=35
Combine 15x and -15x to get 0.
\text{true}
Compare 35 and 35.
x\in \mathrm{C}
This is true for any x.
