Answer 2

To solve this expression, you'll need to perform the operations step by step. Here's the solution:

1. First, let's simplify the expressions on both sides of the equation:

   Left side: 4 1/2x + 3 3/10x * 5

   Right side: 7 6/13 + 18 7/13

2. Now, let's simplify each side further:

   Left side: (9/2)x + (33/10)x * 5 (9/2)x + (33/2)x

   Right side: To add these mixed numbers, you'll need to find a common denominator, which is 13: 7 6/13 + 18 7/13 = (7 + 18) + (6/13 + 7/13) 25 + (13/13) 25 + 1

3. Now, let's simplify both sides:

   Left side: (9/2)x + (33/2)x = (9/2 + 33/2)x (42/2)x = (42/2)x

   Right side: 25 + 1 = 26

4. Now, both sides of the equation are simplified:

   Left side: (42/2)x = 21x Right side: 26

5. Finally, solve for x by dividing both sides by 21/2:

   (42/2)x = 26 (21)x = 26 x = 26 / 21

So, the solution for x is:

x = 26 / 21

You can leave it as a fraction or convert it to a mixed number or decimal if needed.
