Please help me. I need help. Answer question please!

6(5-a) - (1-a) = 2

First distribute (multiply) the 6 across the terms in the parentheses:

6*5 - 6*a - (1-a) = 2

30 - 6a - (1-a) = 2

When you subtract terms within parentheses, such as -(1-a), change the sign of each term and add them; that is -(1-a) = + (-1) + a = -1 + a:

30 - 6a + (-1) + a = 2

30 - 6a - 1 + a = 2

Combine like terms:

(30-1) + (-6a+a) = 2

29 - 5a = 2

Now solve for a:

29 - 2 = 5a

27 = 5a

**27/5 = a**
