Решение во вложении----------------------

Answer 2

To solve the system of equations:

а + 3в + 1/3а + в - 1 = 2

We can simplify the equation by combining like terms:

4/3а + 4в - 1 = 2

Next, we'll isolate the variable а:

4/3а = 2 - 4в + 1

4/3а = 3 - 4в

Now, let's multiply both sides of the equation by 3 to eliminate the fraction:

4а = 9 - 12в

We can rewrite this as:

4а + 12в = 9

Now, let's solve the expression 10а - 2в + 8 using the values of а and в obtained from the previous equation:

10(9/4) - 2в + 8 = 90/4 - 2в + 8 = 22.5 - 2в + 8 = 30.5 - 2в

Therefore, the simplified expression is 30.5 - 2в.
