Question

4а+2(2а-3в) если 3в-4а=2

Answer 1

4а+2(2а-3в)=?, если 3в-4а=2
4a+4a-6b=8a-6b=-2*(3b-4a)=-2*2=-4;

Answer 2

To simplify the expression 4а + 2(2а - 3в) when 3в - 4а = 2, we need to substitute the value of (3в - 4а) with 2 in the given expression.

So, start by substituting the value of (3в - 4а) in the expression:

4а + 2(2а - 3в) = 4а + 2(2а - 3в)

Now, replace (3в - 4а) with 2:

4а + 2(2а - 3в) = 4а + 2(2а - 2)

Next, simplify the expression within the parentheses:

4а + 2(2а - 2) = 4а + 2(2а - 2) = 4а + 2(2а) - 2(2)

Now, multiply 2 by (2а) and 2 by 2:

4а + 2(2а) - 2(2) = 4а + 4а - 4

Combine like terms:

4а + 4а - 4 = 8а - 4

So, the simplified expression is 8а - 4.
