Final answer:
To solve absolute value equations, isolate the absolute value expression and solve for the variable inside. For a) 3(y - 2) = 120, the solution is y = 42. For b) 4(n + 5) = 40, the solution is n = 5.
Step-by-step explanation:
To solve the absolute value equations, we need to isolate the absolute value expression and then solve for the variable inside the absolute value symbol. Let's solve the given equations:
a) 3(y - 2) = 120:
- Distribute the 3: 3y - 6 = 120
- Add 6 to both sides: 3y = 126
- Divide by 3: y = 42
b) 4(n + 5) = 40:
- Distribute the 4: 4n + 20 = 40
- Subtract 20 from both sides: 4n = 20
- Divide by 4: n = 5
