Question

Solve 3/5k-5=7/10k by eliminating the fraction. Explain how you determine what to multiply each term by and all the steps to solving the equation.

Answer 1

9514 1404 393

Answer:

k = -50

Explanation:

The fraction denominators are 5 and 10. The least common multiple of those values is 10. This means we can eliminate fractions by multiplying both sides of the equation by 10:

6k -50 = 7k

Subtracting 6k from both sides of the equation leaves you with the solution:

-50 = k
