Answer 2

To simplify the expression (2/3а-1)(6б+1)-(4-2а)(2/3-2б), let's perform the calculations step by step:

First, let's expand the first part of the expression:

(2/3а-1)(6б+1) = (2/3а)(6б+1) - 1(6б+1) = (12/3аб + 2/3а) - (6б + 1)

Next, let's expand the second part of the expression:

(4-2а)(2/3-2б) = (4)(2/3-2б) - (2а)(2/3-2б) = (8/3 - 8б) - (4а/3 - 4б)

Now, we can simplify the expression by combining like terms:

(12/3аб + 2/3а) - (6б + 1) - (8/3 - 8б) + (4а/3 - 4б)

Combining like terms, we get:

(12/3аб + 2/3а - 8/3 + 8б) - (6б + 1 - 4а/3 + 4б)

Simplifying further:

12/3аб + 2/3а - 8/3 + 8б - 6б - 1 + 4а/3 - 4б

Now, let's combine the like terms:

(12/3аб - 6б) + (2/3а + 4а/3) + (8б - 4б) + (-8/3 - 1)

Simplifying each part separately:

(4аб - 6б) + (2а/3 + 4а/3) + (4б) + (-11/3)

Combining like terms again:

4аб - 6б + (6а/3) + 4б - 11/3

Simplifying further:

4аб - 6б + 2а + 4б - 11/3

Finally, combining like terms for the last time:

4аб + 2а - 6б + 4б - 11/3

The simplified expression is:

4аб + 2а - 2б - 11/3
