Answer 1

7a/6c -(49a²+36c²)/42ac+(6c-49a)/7a=
=(49a²-49a²-36c²+36c²-6c*49a)/42ac=-6c*49a/42ac=-7

Answer 2

Calculating the Expression

To find the value of the given expression 7a/6c - 49a + 2 + 36c + 2/42ac + 6c - 49a/7a, we can follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Step 1: Simplify the Expression

First, let's simplify the expression step by step:

1. 7a/6c - 49a 2. + 2 3. + 36c 4. + 2/42ac 5. + 6c 6. - 49a/7a

Step 2: Perform the Calculations

Now, let's perform the calculations for each part of the expression.

1. 7a/6c - 49a: - We can simplify this part further by factoring out the common term 'a': a(7/6c - 49).

2. + 2 3. + 36c 4. + 2/42ac: - This can be simplified to 1/21ac.

5. + 6c 6. - 49a/7a: - This can be simplified to -7.

Step 3: Combine the Results

Now, let's combine the results of the simplifications:

a(7/6c - 49) + 2 + 36c + 1/21ac + 6c - 7

Step 4: Evaluate the Expression

Finally, we can evaluate the expression using the given values of 'a' and 'c'.

Let's proceed with the calculation based on the given expression and the simplified form.
