7|d+143|+9=72
Swap sides so that all variable terms are on the left hand side.
7|d+143|=72-9
Subtract 9 from both sides.
7|d+143|=63
Subtract 9 from 72 to get 63.
|d+143|=\frac{63}{7}
Divide both sides by 7.
|d+143|=9
Divide 63 by 7 to get 9.
d+143=9 d+143=-9
Use the definition of absolute value.
d=-134 d=-152
Subtract 143 from both sides of the equation.
