Question

2*(4a-5b)+(4a-7b) - 3 *(6a-8b)

Answer 1

8a+10b+4a-7b+18a+24b = 30a+27b

Answer 2

8а-10b+4a-7b-18a+24b= -6a+7b

Answer 3

Let's simplify the given expression step by step:

Expression: 2*(4a-5b) + (4a-7b) - 3*(6a-8b)

Step 1: Distribute the coefficients 2 * 4a - 2 * 5b + 4a - 7b - 3 * 6a + 3 * 8b

Step 2: Perform the multiplications 8a - 10b + 4a - 7b - 18a + 24b

Step 3: Combine like terms (8a + 4a - 18a) + (-10b - 7b + 24b) -6a + 7b

So, the simplified expression is -6a + 7b.
