Question

3 (a+b) - 4(2а-b) + a​

Answer 1

Ответ:

3(a+b)-4(2a-b)+a=3a+3b-8a+4b+a= - 4a+7b

Answer 2

To simplify the expression, let's first expand the terms and then combine like terms:

3(a + b) - 4(2a - b) + a

Step 1: Distribute the coefficients

3a + 3b - 8a + 4b + a

Step 2: Combine like terms (terms with the same variable raised to the same power)

(3a - 8a + a) + (3b + 4b)

Step 3: Perform arithmetic operations

(-4a) + (7b)

The simplified expression is:

-4a + 7b
