Answer 2

To simplify the expression, follow the order of operations (PEMDAS/BODMAS - Parentheses, Exponents, Multiplication and Division, Addition, and Subtraction):

Given expression: 7(4a + 6) - 12a

Step 1: Distribute the 7 to the terms inside the parentheses: 7 * 4a + 7 * 6 - 12a

Step 2: Perform the multiplication: 28a + 42 - 12a

Step 3: Combine like terms (terms with the same variable 'a'): (28a - 12a) + 42

Step 4: Simplify the coefficients: 16a + 42

So, the simplified expression is 16a + 42.
