Answer 2

To solve this equation, you can follow these steps:

1. Start by simplifying each side of the equation separately.

On the left side, you have:

(18/x) / (54/85)

To divide by a fraction, you can multiply by its reciprocal. The reciprocal of (54/85) is (85/54).

So, (18/x) / (54/85) = (18/x) * (85/54)

On the right side, you have:

(54/85) / (63/17)

Again, to divide by a fraction, multiply by its reciprocal. The reciprocal of (63/17) is (17/63).

So, (54/85) / (63/17) = (54/85) * (17/63)

Now, the equation becomes:

(18/x) * (85/54) = (54/85) * (17/63)

2. Simplify both sides further by canceling out common factors and multiplying.

On the left side:

(18/x) * (85/54) = (18 * 85) / (x * 54) = (1530/x)

On the right side:

(54/85) * (17/63) = (54 * 17) / (85 * 63) = (918/5355)

Now, the equation is:

(1530/x) = (918/5355)

3. Cross-multiply to solve for x:

1530 * 5355 = x * 918

8193150 = 918x

4. Finally, solve for x by dividing both sides by 918:

x = 8193150 / 918 x ≈ 8921.52

So, the value of x is approximately 8921.52.
