Answer 3

To solve for x in the equation:

12(1 3/4x + 5/8) = 8 1/2

First, simplify the equation by multiplying out the terms on the left side:

12(1 3/4x + 5/8) = 8 1/2

Now, distribute the 12 on the left side of the equation:

12 * 1 + 12 * (3/4)x + 12 * (5/8) = 8 1/2

12 + (9/4)x + (15/2) = 8 1/2

Now, let's get rid of the fractions by multiplying both sides of the equation by 4 to clear the fractions:

4 * (12 + (9/4)x + (15/2)) = 4 * (8 1/2)

48 + 9x + 30 = 34

Now, subtract 78 from both sides to isolate the term with x:

9x + 30 = 34 - 48

9x + 30 = -14

Next, subtract 30 from both sides to solve for x:

9x = -14 - 30

9x = -44

Finally, divide both sides by 9 to find the value of x:

x = -44 / 9

So, the solution for x is:

x = -44/9
