Answer 2

To simplify the expression 4(3-a)-5(1+0.2b), you can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction:

Given expression: 4(3-a) - 5(1 + 0.2b)

Step 1: Distribute the numbers outside the parentheses/brackets: 4 * 3 - 4 * a - 5 * 1 - 5 * 0.2b

Step 2: Perform the multiplications: 12 - 4a - 5 - 1b

Step 3: Combine like terms: (12 - 5) - 4a - b

Step 4: Simplify further: 7 - 4a - b

So, the simplified expression is 7 - 4a - b.
