Hi there!
We are given the equation 15 - 5(4x - 7) = 50 and are told to solve for x. Well, we can start off by using the distributive property, which gives us 15 - 20x + 35 = 50. Now, we combine like terms, which simplifies the equation down to 50 - 20x = 50. Now, subtract 50 from both sides - -20x = 0. Finally, divide both sides by -20. Therefore, the answer to your query is x = 0. Hope this helps!
