Answer 2

Solving the Equation

To solve the equation provided, let's break it down step by step:

1) 3(1/9x + 1/5) + 2 + (3/8 + u - 1/4) * 2 + 3 + (1/6 + 5/12x)

First, let's simplify the expression inside the parentheses:

- 1/9x + 1/5 = (5x + 9) / 45 - 3/8 + u - 1/4 = (6u - 1) / 8 - 1/6 + 5/12x = (3x + 1) / 6

Now, let's substitute these simplified expressions back into the original equation:

- 3((5x + 9) / 45) + 2 + ((6u - 1) / 8) * 2 + 3 + ((3x + 1) / 6)

Next, let's simplify the expression further:

- (15x + 27) / 45 + 2 + (12u - 2) / 8 + 3 + (3x + 1) / 6

To add the fractions, we need to find a common denominator:

- The common denominator for 45, 8, and 6 is 360.

Now, let's rewrite the expression with the common denominator:

- (8(15x + 27) + 2(45) + 45(12u - 2) + 8(3) + 6(3x + 1)) / 360

Simplifying further:

- (120x + 216 + 90 + 540u - 90 + 24 + 24x + 8) / 360

Combining like terms:

- (144x + 540u + 198) / 360

Simplifying the expression:

- (12x + 45u + 33) / 30

Therefore, the solution to the equation is (12x + 45u + 33) / 30.
