How do you solve #-7+8abs(-7x-3)=73#?
See the entire solution process below:
The absolute value function takes any negative or positive term and transforms it to its positive form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent.

To solve the equation -7 + 8| -7x - 3| = 73:
- Add 7 to both sides: 8| -7x - 3| = 80.
- Divide both sides by 8: | -7x - 3| = 10.
- Break into two cases: a) -7x - 3 = 10 b) -7x - 3 = -10
- Solve each case separately: a) -7x = 13 Divide by -7: x = -13/7 b) -7x = 7 Divide by -7: x = -1
Therefore, the solutions are x = -13/7 and x = -1.
