15|x-7|+4-10|x-7|=4
Subtract 10|x-7| from both sides.
5|x-7|+4=4
Combine 15|x-7| and -10|x-7| to get 5|x-7|.
5|x-7|=4-4
Subtract 4 from both sides.
5|x-7|=0
Subtract 4 from 4 to get 0.
|x-7|=0
Divide both sides by 5. Zero divided by any non-zero number gives zero.
x-7=0
Use the definition of absolute value.
x=7
Add 7 to both sides of the equation.
