Question

# Simplify: 12 - [13a - 4(5a -7) - 8 {2a -(20a - 3a)}]

Hint:

○ Perform basic arithmetic operations to simplify expression.

## The correct answer is: 113a - 16

### Answer:

Step by step explanation:

○ Given:

Expression:

12 - [13a - 4(5a -7) - 8 {2a -(20a - 3a)}]

○ Step 1:

○ Simplify:

12 - [13a - 4(5a -7) - 8 {2a -(20a - 3a)}]

12- [13a - 20a + 28 - 8 {2a - 17a}]

12- [- 7a + 28 - 8 {- 15a}]

12- [- 7a + 28 - {- 120a}]

12- [- 7a + 28 + 120a}]

12- 28 + 113a

113a - 16

- Final Answer:

113a - 16
