Final answer:
To solve the equation 5|y+1|-40=0, isolate the absolute value, consider both cases (positive and negative), and solve for y to obtain two solutions: y = 7 and y = -9.
Step-by-step explanation:
To solve the equation 5|y+1|-40=0, let's first isolate the absolute value expression:
- Add 40 to both sides to get 5|y+1| = 40.
- Divide both sides by 5 to get |y+1| = 8.
- Now, solve for y by considering the two cases for the absolute value:
Therefore, the solutions for the given equation are y = 7 and y = -9.
