Answer 2

Let's solve the equation step by step:

1. Start with the equation: 6(4 + a) + 8(a - 6) = R - (17 - R) + (-R + 30).

2. First, simplify the expressions within the parentheses on both sides of the equation:

   6(4 + a) + 8(a - 6) = R - 17 + R + (-R + 30).

3. Now, simplify the expressions further by distributing the constants outside the parentheses:

   24 + 6a + 8a - 48 = R - 17 + R - R + 30.

4. Combine like terms on both sides of the equation:

   14a - 24 = 2R + 13.

5. Move the constants to one side and the variables to the other side:

   14a - 2R = 37.

6. Divide both sides by 2 to solve for R:

   7a - R = 18.5.

So, the solution to the equation is R = 7a - 18.5.
