Question

1) - (5а + 8b)— 2b - За – (-10а + 4b)​

Answer 1

-5а -8b -2b-3a+10b-4b= 2a -14b = 2(a-7b)

Answer 2

It seems like you've provided an expression with variables a and b, and you want to simplify it. Let's break it down step by step:

Expression: 1 - (5a + 8b) - 2b - 3a - (-10a + 4b)

Step 1: Distribute the negative sign inside the parentheses: 1 - 5a - 8b - 2b - 3a + 10a - 4b

Step 2: Combine like terms (terms with the same variables): (1 - 3a + 10a) + (-5a - 8b - 2b - 4b)

Step 3: Simplify the constants and the 'a' terms separately: (1 + 7a) + (-5a - 8b - 2b - 4b)

Step 4: Combine like terms in the 'b' terms: 1 + 7a - (5a + 8b + 2b + 4b)

Step 5: Continue simplifying: 1 + 7a - (5a + 14b)

Step 6: Distribute the negative sign inside the parentheses again: 1 + 7a - 5a - 14b

Step 7: Combine like terms: (1 - 5a) + (7a - 14b)

Step 8: Simplify the constants and the 'a' and 'b' terms separately: -4a + (7a - 14b)

Step 9: Combine the 'a' terms: (7a - 4a) - 14b

Step 10: Simplify further: 3a - 14b

So, the simplified expression is 3a - 14b.
