Ok, so, I am looking up how to solve 4x + 8 = -7x + 19 and I scrolled down to my search engine's answer and it said x = 1. Ok, well, then I scrolled down a little further and clicked on a link and they showed you how to do it but the second website said x = -1. Which one is right? Please help, I really struggle with math a lot and now these two different answers are confusing me even more. If you can also explain why which of the two answers are correct that would be amazing! If you can't answer please comment! Thank you so so so much!!!

Answer: X=1

Explanation:

Add 7x over to the 4x to get 11x. 11x+8=19 subtract 8 on both sides to get 11x=11. Divide and you get 1.

Answer:

x = 1

Explanation:

4x + 8=-7x +19

add 7x to both sides

4x + 7x+8=-7x+7x +19

11x + 8=19

subtract 8 from both sides

11x + 8-8= 19-8

11x=11

x = 1
